HK SP5K Photo Shoot In The Leaves

Okay, I liked the leaves, the lighting and thought it would be a great chance to get some photos of the HK SP5K pistol with the SB Tactical SBTK5A brace and the Vortex Optics Crossfire red dot that is on an American Defense AD-T1-L STD quick release mount.  As you can see above, I’m still using the Uncle Mike’s case.

So those are a few from the batch.  Looking forward to taking it to the range some day.

Basic SubGun Case for HK SP5K with Brace

As I wrapped up my changes on the SP5K, I realized I needed a case to put it in.  It just so happened that I had an Uncle Mike’s “Tactical Submachine Gun Case” that I had never used and it turns out the SP5K with the SB Tactical SB5KA brace and Vortex Crossfire red dot could slide right in without the magazine installed.

This is the front of the bag – six magazine pouches, one large flat pouch to the front and the rear mounted carry handle is visible.
This is the back – you can see the shoulder strap and the carry handle at the top.

The case has a zipper at the rear of the bag and the SP5K simply slides in.  This is one thing I dislike – it does not open and lie flat.  Some folks may find this a plus but I prefer bags that open.

The exterior dimensions are 24.5x14x2 and I’d knock off about half and inch all the way around for the interior dimensions.  It does have some padding but not a ton.

Another dislike I have is the way it holds the MP5 magazines.  They slide down in the little pouches and I can’t pull them out.  I need to push at the bottom to get them to slide up.

I pushed the magazines up so you can see them in this photo.  Notice where the bulges indicating the actual lower part of the magazine in each pouch.  In practice, the mags slide all the way down and are hard to get out.  You have to press from the bottom.

On the topic of pouches, the front pouch just forward of the magazines is very tight.  The bulge you see sticking out is a Mag Lula loader.  While it can hold the loader, it’s really better suited for thinner items.

Okay, rounding out my complaints, the carry handle at the rear makes for an odd front-loaded unbalanced load.  I don’t know why they didn’t center it.

Summary

It’s a decent entry bag for only $27.95 with Prime shipping on Amazon.  Sure there are things I don’t like about it but does the job.   I will be investigating other cases but this case is a solid performer at the price.

Picking an Optic for HK SP5K

In past posts, I have written about buying the SP5K, selecting a brace and the forearm.  Next up is the optic.  It should come as no surprise that my go to brand is Vortex Optics.

I’m a creature of habit.  Vortex products are solid and have a no-nonsense – “if it breaks we will fix it” – warranty.  Vortex does not sponsor me so I have no reason to stick with them other than they deliver.

I knew right way this was going to be a close-in weapon with distances being typically 25 yards or less but maybe stretching out to 50 yards.  It is hard to beat a red dot at those distances for rapid target acquisition.  That narrowed my options down quite a bit.

A second big deal for me is to have a wide field of view but also a relatively small dot size.  This combination rules out a lot of the micro dots that are out there as they are both tiny and have a 4 MOA dot size – that means the red dot will cover 4″ and 100 yards or about 2″ at 50.  The micro dots are okay and I rather like them on pistols but I wanted something a tad finer on this more controllable and accurate weapon.

The Vortex Crossfire Red Dot

All paths lead me to the current Vortex Optics Crossfire red dot. It has a 2 MOA dot size, is only 2.5″ long and only weighs 5.2oz.  It also has a battery life of 7,000 hours at an output setting of 5.  Note the optic has 11 levels so when you have it turned up for bright light settings, you will drain the battery faster – always keep a spare battery in the case.  I’ve had a couple of range sessions get messed up to do dead/dying batteries and no spares.

American Defense AD-T1-L STD Mount

The only shortcoming, if I can even call it that, with the Crossfire is its base.  Vortex did their homework and include both a short base and base that can lower 1/3 co-witness with AR iron sights.  The problem is that they are screwed onto the picatinny rail.  If you need to get the optic off fast, that’s not going to happen as you will need a torx driver.

I do have good news – the Crossfire has the same base geometry as the Aimpoint T-1/H-1 optics.  That’s the key right there – there are a lot of mounting options out there and after some digging, I have been using mounts from American Defense for over a year and they are rock solid.

By the way, make sure you get the right mount – American Defense makes there base for a variety of optics.  I am using the AD-T1-L STD.

Assembling the Optic on the Mount

The good news is that this is really easy.  Undo the four screws on the bottom of the Crossfire to remove the Vortex mount.  Put the American Defense mount underneath it, add a bit of Blue Loc-Tite thread locker and reinstall the screws.

Use the small Torx wrench that Vortex supplies with the Crossfire to remove the four screws so you can the swap the bases.
Here you can see the bottom of the Crossfire and how the American Defense mount will align.
You can see the Blue Loc-Tite and the installed screws.  I like to put the Loc-Tite in the holes and then install the screws.  I wiped the residue away with a paper towel after I took this photo.

The Result

The result turned out really nice.  The optic is just the right height that it is relatively close to the bore and I can get a good consistent cheek weld.

Deciding on the Forearm for my HK SP5K

In my last post, I went over the options I considered for the brace on my HK SP5K.  In this post, I’ll review the three handguards I looked at – the original forearm, a US-made polymer unit with an integral hand stop and a low-profile aluminum unit.

I really have two places I shop for HK and related parts – HKparts.net and RobertRTG.  So I went and checked out what they had plus I did google searches on “SP5K photos” and “MP5K photos” to see what others were using.  I’m a visual guy and can scan a ton of photos very fast and then click to read the articles.

Removing the handguard is pretty much like all other HKs – pop the pin and pull down.  You can see just how short that barrel is due to HK having to comply with German export laws for the pistol to be deemed “sporting purpose.”  This also means you need to carefully think how to keep your fingers, notably your thumb, out of the way.  You could argue training and holding the mag well but… there is a risk no matter what.

After researching for a bit, I got it down to the following three options that I could afford to try out:

Option 1:  The Original Forearm

The unit that comes with the SP5K has two things going for it – the hand stop and the muzzle guard.  The little indentations you see on the sides are actually thumb rests.  From a safety perspective, this seemed like the best but I wasn’t sure about how the muzzle protector would hold up over time.

Note the thumb rest of the muzzle guard area of the original SP5K handguard.  The hand stop is well forward giving you plenty of grip options also.
See, the actual end of the muzzle is located way down in the guard.  I can’t help but wonder how the polymer will hold up over time.  I’m betting HK thought about that is why they made the guard so much wider than the muzzle to allow most of the blast cone to pass by without contacting the polymer.  I haven’t heard of folks having problems so HK must have designed it correctly.

Option 2:  A US-made Polymer Handguard Sold by HKParts.net

The second option I decided to try was a US made “Reverse stretch forearm with hand stop” that was made for HKparts.net.  It was very well, fit my SP5K great and had great room for my hand but the problem was my thumb.  It wanted to go in front of the muzzle.



To be clear, it is an excellent handguard.  I blame the German politicians for the abrupt barrel.  If I had a muzzle device out front, this would have made an excellent forearm.

Option 3:  HKParts.net’s Own Low-Profile M-Lok Unit

So this brings us to the last option.  I tend to like the flexibility that rails bring and decided to try another HKParts.net model – their Low Profile Forearm M-LOK.  I ordered an Ergo hand stop/barricade stop to mount on it as well. 


I removed all of the screws to install the unit just in case some wiggling was needed. I think it could have fit without my doing this but I was trying to save the finish.
I knew I was in trouble.  It was going to be way too short and the Ergo hand stop was going to be pushed back into a slot and not going to be able to protrude without some machining.
The Ergo hand stop / barricade stop was well made.  No complaints at all with that part.  It installed just like any M-LOK component does.
Here you can see that the Ergo’s position is constrained by the M-LOK design.
Houston, we have a problem.  I wear XL-sized gloves found the resulting set up way too awkward.  I thought about drilling and tapping the handguard to move the Ergo forward but then I would still have my thumb flopping around.

Bottom line, this just was not going to work as much as I wanted it to.  Blasted politicians.

So What Did I Do?

After trying all three out, I decided to actually stay with the original forearm.  Some day in the future, I will spend the money to have a B&T barrel installed with a tri-lug adapter.  I really like the B&T brake that I run on my POF-5 and will then decide on which of the handguards I want to use.  So, the brace and handguard were both selected, in the next blog post, I’ll discuss the optic I went with and why.

Here she is for the moment.  Note I added a QD Swivel to the mounting point on the brace.

Brace Options for the HK SP5K

In the last post, I told you I bought an SK SP5K.  It’s relatively heavy and begging for a brace.  I don’t really feel the need to spend the money and wait to register it to be a Short Barreled Rifle (SBR) and there are actually a ton of arm brace options out there. 

Option 1:  The SBT5K Brace

I have a SB Tactical SBT5A Brace on my POF-5 and really like it.    I knew they made a version for the SP5 known as the SBT5KA but I was hoping for something different.

Option 2:  The SOB Brace

Every time I write this product name – the “SOB” – down, I smile.  SB Tactical has a ton of braces for the AR/M4 weapons family and they have evolved a ton away from the ugly original.  The SOB has clean lines and I run one on my PTR PDWR.  I think it looks good and has handled the .308 rounds from the PDWR just fine and feels solid too.

Option 3:  The SBPDW

I thought I had found just what I wanted with the SBPDW – a collapsing stock that looked really slick and it would be easy enough to add an M4 adapter to the SP5K.  So, I ordered a very well made adapter from HKParts.net and the expensive SBPDW stock and guess what?  It would not fit.

Needless to say, I was bummed.  I had it completely installed only to find out that the guide rods on the SBPDW run right into the sides of the SP5K.  Crud.  I didn’t feel like figuring out all the changes that would be needed.

Purely for reference, here’s the same stock now installed on a 10.5″ AR Pistol but that is a story for another day.

The Winner?  The SBT5K

Well, I was bumming from the strike out with the SBPDW so I went with my second pick – the SBT5K.  I felt it was most true to the lines of the MP5K and ordered one from RobertRTG who had them on sale.  As with their other braces, SB Tactical did a great job.

Installation was a breeze.  Pull out the two small pins at the back, swap the old end-cap for the brace, push them together and reinsert the pins.  I did make sure the recoil rod lined up and nothing was binding as I reassembled the unit.

I Did Clean and Lube The Internals

I should point out that when I removed the end cap, I went ahead and slid out the bolt group and lubricated everything.  I applied Super Lube grease to the bolt body and Mobil 1 Synthetic 10w30 via a precision oiler to the rollers of the bolt and rotating surfaces.  I also oiled the pins on the trigger pack while greasing the hammer face with Super Lube.

Summary

So you see I went with the SBT5K brace.  In the next post I will discuss handguards.

So, I have an HK SP5K …

Folks, I have thoroughly enjoyed my POF-5, which is an MP5 pistol clone, this past summer.  We easily put way past 500 rounds through it with zero failures to feed or eject.  All my family members and friends wanted to shoot it and we had a ton of fun.  However, in the back of my head, there was a little voice saying “you need a real HK”.

Finding a Real HK

I’d talked to a few guys and the consensus was that a real HK will just go up in value even after being shot plus there are the bragging right of owning a real HK.  There was one problem – HK stopped making MP5s available for civilian sales.  There are definitely a lot of parts kits out there but then someone needs to pay an HK smith to assemble the subgun.  I thought about doing it but I lack the experience and the tooling.  Given the price $1,600-3,200 price of kits, I wasn’t about to experiment.

It turned out that HK still made a civilian pistol – the SP5K – “Sporting Pistol” 5K – that is a semi-auto version of the short MP5K submachine gun.  The one catch is that it comes to the US market a tad neutered.  Surprisingly, this was done due to strict German export laws and not US import laws.   For me, the sad part is that the barrel is 115mm/4.53 inches long and ends abruptly at the sight block – not only is there no threading or tri-lug attachment point but the abrupt end means you can’t add one either without replacing the barrel.  However, accuracy reports are excellent so at least that and reliability were still there.

Before I seriously considered buying one, I did some research:

There are also some choice articles:

Hard to Find an Affordable SP5K

Of course, these things aren’t cheap and they are really hard to find in stock.  I hunted around online while my FFL, Scott Igert of Modern Antique Firearms, did the same.  After hunting for a few weeks it dawned on me that I would need to use GunBroker.  So, I started by watching auctions and seeing what stuff sold for before I started actually bidding and losing.  I learned a while ago not to chase auctions – set a price and don’t go past that limit.  I finally found a deal after watching and bidding for over a month. 

So, the seller was Town Police Supply, located in Collinsville, VA, who goes by GunTalker on GunBroker.  They had an A+ reputation with over 700 trades.  I always prefer to deal with sellers that have a lot of trades.  At any rate, they were great to deal with.  I won the auction on 9/24/18 and it arrived at Scott’s shop on 9/25.  Literally.

As you can imagine, I picked the SP5K up as soon as I could.  It came in a real cool HK hard case with two 10 round magazines, a sling and a sight adjustment tool as you can see in the featured photo at the top.

Here’s the plain pistol out of the box:

In summary

So, it was definitely cool but if you know me, you also know what was going through my head – “I can customize this!”  In my next blog post, I’ll talk about what I considered for braces.

Customizing and Shooting the Pakistani Ordnance Factory POF-5 Pistol

Having watched one too many TV shows and movies with H&K’s MP5 submachine gun over the years, the sub gun has been on my “I want to have one list” for years but way out of my price range.  While surfing, I read about how Pakistani Ordnance Factory (POF) licensed the design and tooling necessary from H&K Germany to make roller locked weapons including MP5 clones.  In reading about the various Mp5 clones,  it became apparent that the POF-5 units are actually well regarded.  What really tipped the scales was a great post by T. Mark Graham at Arizona Response Systems who really knows his way around MP5s saying they were good to go with details of his analysis provided.

This led me to calling up Chuck at Kelly Enterprises and talking about whether to buy a Zenith (my first choice) or a POF.  Chuck is a very straight forward guy and tells it the way it is.  The Zenith would be hard to get and he had POF-5 pistols in stock plus he gave me a great deal so I ordered one and had it sent to my friend and FFL, Scott Igert, at Modern Antique Firearms.  Chuck sent me all the tracking info and just a few days later, the POF-5 was with Scott waiting for me to pick it up.

On inspection you could tell the receiver paint was a bit glossier than the more satin finish of an HK but other than the action feeling dry and new (that gritty not worn in feeling), it looked good to go.

Now, I have two personality quirks.  First, I can’t hit the broad side of a barn with a pistol let alone one this big and heavy.  Second, I can’t help but customize any gun I buy and this wasn’t any different.

I did a ton of reading and decided to go with a cool S&B brace, a B&T scope mount, Dakota Tactical handguard, a B&T muzzle brake and ordered a bunch of POF MP5 magazines.  I bought my stuff from HKparts.net and everything showed up promptly.

Installing the brace was easy – like any HK, you push out the rear pin, pull off the cap and put on the brace.  I bought one all ready to go.

The handguard is a keymod unit from Dakota Tactical and they use a screw instead of a front pin to hold the unit in place.  It really locks up nice and I like the feel of it.  The rail section holding the Streamlight in the below photo is made by Monoki.

Now the scope mount is the standard B&T universal rail, the BT-21262-1.  I would caution against you buying a cheap optics mount for an HK-type weapon.  There are tons of stories of cheap ones falling off, not seating properly, etc.  The B&T unit is a mil-grade unit.  You slide it on and then work the little claws or feet into position and then secure them with the supplied screws.

Next up  was to install the Vortex Crossfire Red Dot optic.  These are the latest red dots from Vortex and come with both low and high mounting options.

Out of the box it has the high mount installed for the AR enthusiasts but includes the low plate as well.

As you can see, with the default high riser on it, the optic is way too high.  I prefer optics as low as possible where I can get a good cheek weld.

It’s real easy to change – there are just four screws that need to be removed on the bottom.  I used a bit from my Weaver driver set vs. the supplied key which would work but is slow compared to a driver.

I have the Weaver Deluxe Tool Kit and use the drivers all the time.  I use the block and hammer some but not a great deal.

Notice that Loc-Tite Blue (the medium strength formula) is used to secure the screws.

Here’s the end result.  Note, I will install a quick release mount at a later date.

One side comment – you may find it funny that the thing that puzzled me most was the B&T brake.  It installs on the tri-lobe fitting on the muzzle. There is a quick release lever that baffled me until I carefully inspected it and saw that one end is open and a cross pin is retaining it.  I then pushed the other way and lever lifted right up.  Duh!  I’d never seen one before!  It is solid and I like it.

The case you see is a 32″ Blackhawk Homeland Security Weapons Carry Case.  It comes with one internal mag carrier and I added a second pouch.  They are sized for 30 round AR mags and you can get two 30-round MP5 magazines in each pouch pocket.

Next up, I cleaned the bore and lubricated the weapon – especially the bolt head and trigger pack.  Past experience taught me to go through and make sure it was ready.

Two of my brother-in-laws and I took it to the range.  We used 124 grain S&B FMJ ammo and it functioned great and was accurate.  We had a blast at 15-25 yards shooting it despite it being a brisk day.  I really like how this combination worked out.  We didn’t use the light but the green laser was nice and bright when we tried it out.

We put probably about 200 rounds through it.  You can now feel the action has really smoothed out and I wouldn’t hesitate using this for home defense if I needed – which is why I put the light on it.

All in all, I’m very pleased and would recommend the POF-5 to anyone looking for a semi-auto MP5-type pistol.

Update 10/6/2018:  We put almost 500 rounds through this pistol this summer without one single failure to feed or eject.  We mainly shot the 124 grain FMJ S&B ammo except for one time, as a test, I shot about 20 rounds of Hornady 135gr Critical Duty ammo with no problem.  All of the magazines used (and I have 10 of them) are POF magazines.  Honestly, this thing is awesome.  I’ve only cleaned and re-lubed it once so far but it is on the to-do list.

Shooting the PTR PDWR – So Cool!

Folks, the PTR PDWR is a fun gun!  Yeah, I said the “gun” word because it just fits.  After taking the time to lubricate and clean the pistol as I wrote in the last post, my two brother-in-laws and I took it out to the range.

Plain and simple, it ran like a top.  We did not have one single problem of any kind.  We were running surplus aluminum mags from Robert RTG.  The ammo was Prvi Partizan (PPU)  .308 M80 145gr FMJ.  I’ve had great luck with PPU ammo over the years and have run a variety of their calibers and loads.  This .308 ammo comes in a heavy plastic sealed “battle pack” that SGAmmo sells.  If you don’t know SG Ammo, they are a great ammo supplier that is a family run business.  I buy most of my ammo from them and have nothing but good things to say about them.

We sighted the Vortex 1-6×24 Strike Eagle scope in at at about 25 yards and then just had fun.  We weren’t shooting for accuracy but were having fun shooting “zombies” as we called them with the big Splatterburst 18×24 silhouette targets that I really like.

This time out, I was using my new Howard Leight electronic ear muffs.  These are cool because they have directional sound amplification for normal sounds – like talking with your friends.  When you shoot, they immediately cut the sound off and protect your ears.  This is a real nice feature for me as I can’t hear a thing when I wear ear muffs due to my hearing loss and have to take them off to talk to someone.  At any rate, these Howard Leights have a great reputation and I must say that I am very happy with them.

One of my brother-in-laws was wearing my new MPOW headphones and thought they did a really good job on cutting down the sound.  These are a bargain price at Amazon and work way better than my old cheap Silencios in terms of hearing protection.

Now we did have a funny lesson learned – see how short the barrel is relative to the Caldwell front bag?  Yeah, if you get the muzzle brake over that bag and fire, it will rain some kind of brown pebbles (corncob media maybe?) down on you as the muzzle blast shreds the top of the bag 🙂  I have to confess, I am the one who did it and had to use duct tape to seal the top up so we could use it the rest of the day.

The whole point of the range visit was for me any my two brother-in-laws to have fun and function test the PDWR.  It performed admirably – neither of them are shooters and, for Jamie, this was his first time shooting anything – I think he did great.

Not one single problem – no feed issues, no ejection issues – it just performed great through about 200 rounds.

At any rate, I did learn a few things:

  1. It upheld the good opinion I have of PTR firearms.
  2. The SOB brace can handle .308 recoil just fine and lines the eye up for the scope great.
  3. As expected, the Vortex scope was great.
  4. The weight of the PDWR absorbs quite a bit of recoil making it a pleasant shooter but there is still recoil that moves you off target with any kind of rapid fire.
  5. The muzzle brake does an okay job but I am going to check into alternatives to cut the recoil down further.  The bird cage design is okay but there are definitely better designs out there.  The PDWR has a 5/8″-24 TPI threading so there are definitely options.
  6. The PDWR handguard moves forward and backward more than I care for.  I am going to experiment on tightening it up or either moving to a DTAC handguard or back to the original PTR handguard.  Note – the PDWR uses a MP5-style handguard.

Bottom line, I am very happy with the PDWR and plan to work with it some more on the above plus see how it does as I work my way back to 100 yards.  Everything in this sessions was at 25 yards or less and I am curious how it performs as the distance grows.  I would recommend the PDWR to anyone looking for a short HK91/G3-type roller lock for short distance use.

Lubricating the PTR PDWR and Cleaning the Barrel

The last step in preparation for my first trip to the range was to clean and lubricate the PTR PDWR.   One thing I learned with my for PTR was that proper lubrication makes a world of difference and I could tell in working the PDWR that it definitely need lubricating so here’s what I did.

If you have any questions about field stripping, watch this video:

Also, if you need any parts diagrams or more detailed questions, be sure to read the HK G3 Armorer’s Manual.

In general, you know you need to lubricate all moving parts of the firearm such as the trigger and bolt.  So let’s start with the trigger.

Lubricating the Trigger Pack:

I employ a very old rule of thumb – If it slides, grease it.  If it rotates, oil it.  That simple rule has helped me take care of a ton of rifles and pistols over the years and can help you too.  [Click here for more on lubricating a firearm in general]

I used a small squeeze bottle filled with Mobil 1 Full Synthetic 5W-30 to reach in and lubricate all places where a part rotated on a pin.  I then worked the various parts of the trigger pack to make sure the oil go to where it needed to go.I used Tetra Gun Grease to liberally coat the top of the hammer.

Lubricating the Bolt Assembly:

Now the HK bolt assembly is involved and the following is a diagram from the HK G3 Armorer’s Manual:

 

In short, I oiled all of the internals but did not fully disassemble the bolt.  I put the assembly into a non-marring vise, twisted the bolt head off and then reached in with the squeeze bottle to lubricate the rollers, locking piece, firing pin, etc.

After that I applied a thin coat of Tetra Grease to the bolt carrier body and put more on the bottom and sides of the bolt where it would be making contact with the receiver and riding over the hammer.

Cleaned the Barrel:

One thing I always do before heading to the range is to clean the barrel.  If you look down in most, you will see varying levels of crud ranging from oil to dust to stuff left over from machining.  In the case of the PDWR, the barrel looked pretty good but I still wanted to clean it.

Over the years I have tried all kinds of different approaches to cleaning barrels.  The fast and easy one I use now on non-precision firearms that just need a touch up is a bore snake.   These things are caliber specific and give you everything you need in an “all in one approach”.  I spray CLP on the snake and down the barrel then I drop the weighted cord down the barrel and pull the snake on through.  I repeat this until the bore is shiny bright.

Note, there are a ton of brands including cheap generic imports.  I’ve used Hoppes and Sage & Braker brands with no problems at all.

At this point the PDWR was ready for the range.  The action felt and sounded good.

Fixing a Bent Sight and Cocking Lever Tube Bur On The PTR PDWR

Okay, when I received the PTR PDWR I did a quick inspection and noticed two small problems that needed fixing.  I’m a bit disappointed that PTR quality control did not catch these two items but they are small issues.

First, the front sight blade was bent sideways – to canted, bent.  I’m not sure how this happened but thankfully the HK-style hooded sight uses a sheet metal insert for the front post.  The following illustration is from the HK G3 Armorer’s Manual:

I figured the easiest thing to try was to simply reach in with pliers with padded jaws and see if I could simply bend it to the right to straighten it.  Out came my purple art pliers 🙂  I literally bought these things back in 2013 for some kind of work that required padded jaws.  I don’t recall what and as odd as they look, they have held up to light use.  My only complaint is that the nylon jaw covers can slide off under very much stress but that was not an issue here at all.

They actually fit perfectly and I was able to bend the sight post straight.  Plan B would be to take a pair of needle nose pliers and slide rubber fuel line hose over the jaws.  My one concern would be whether the relatively thin jaws could adequately support the post during bending.  The art pliers below fit and did the job perfectly.

Fixing a Bur on the Cocking Lever Tube

The second problem I needed to fix was a steel bur on the tip of the cocking handle catch.  It bugged me every time my hand hit it and should not have been there.  Here it is in the next photo – sharp and pointing out.

From years of experience, I knew the pistol needed to be field stripped first otherwise the resulting debris would be messing with the action.    The following is a good video on what to do:

In terms of the repair itself, first, I reached in with a Dremel using a small medium grit sanding drum and the tool on slow speed to knock down the sharp irregular edge from the inside.  Take your time – remove a little and look.  Your goal is always to remove as little material as possible.  As the old saying goes, it is easier to take more off than try and put it back on 🙂

In the next photo, you can see the “point” has been sanded down but there is still material on the surface:

Next, I used a 120 grit small flap sander in my bench mounted rotary tool to sand down that lip.  I could have used my Dremel but I use the little flap sander attachment so much that I routinely leave it in my bench tool.

Again, the trick is to go slow and take your time.  After that, I used compressed air to blow out the tube and receiver and then used carb cleaner spray to “wash out” anything that might have stuck and blew it out one last time.  The bur was gone and now it was on to lubricating the weapon.

(Note, that last photo above has the bolt back in when I was testing it later).
