What is a Ferrule on Yugo and AK Rifles?

A ferrule is a metal end cap found on some wood grips and handguards to protect the end grain of the wood from being hammered and splitting open.  They were used on different country’s weapons and are usually not interchangeable between countries.  For example, Bulgarian and Yugo ferrules are different.

Near and dear to me are the metal ferrules on Yugoslav / Zastave wood lower handguards.  The following photo shows a M92 lower and the black metal cap is the ferrule.  This ferrule does not fit everything Yugo – just the M70, M85/92, and M77.  The M72 and M76 are unique sizes.

You have three options when you need a ferrule:  1) Find a used one and this is real hard – try posting in the Marketplace of http://www.akfiles.com and see if they have one.  2) Buy a replica ferrule from us or 3) Simply pry the old ferrule off, put it on the new handguard and the squeeze the tabs shut again with a pair of pliers.

DSC_0320 DSC_0322 DSC_0323

Note if you are putting it on one of our plastic handguards either just set it on it with the ears closed or glue it in place.  Absolutely do not try to squeeze the ears shut — the little metal divots will not dig into our plastic and you risk snapping the handguard tabs.  Again, either slide it on or glue it in place with something like rubber glue or Goop that you can later remove if you want.  Epoxy works too but it is pretty permanent.

For example, I just slid the ferrule on the M70 bulged handguard in the next photo.

I hope this helps!

How to Install Ronin’s Grips M92 Handguards

This is another long overdue step by step guide.  We have been selling M92 handguards for over two years and people ask about how to install them so let’s try and take this step by step.

SAFETY STEP – MAKE SURE THE WEAPON IS UNLOADED.  NEVER ASSUME THAT IT IS – VERIFY IT IS UNLOADED BEFORE YOU BEGIN WORK.

1.  Open the dust cover so the gas tube can be removed.

DSC_0290 DSC_0292

2.  Take a look at the upper portion.  The gas tube cover is actually a semi circle held in a groove formed by sheet metal.  To remove the cover, secure the forged metal end of the tube (NOT THE SHEET METAL END OR IT WILL BEND) in a vise or use an open end wrench.  Turn the cover 180 degrees until it faces the opposite way and it will come right out of the retainer.

DSC_0293 DSC_0294 DSC_0295 DSC_0296 DSC_0298 DSC_0299

3.  See the metal clip in the gas tube cover?  You will want to move that clip to our gas tube cover as it helps secure it in place.

 

 

 

 

DSC_0300 DSC_0301 DSC_0302

4.  Next, look at the lower handguard.  In the front of the guard on the left side you will see a small lever that needs to be rotated inward.  Once that is done, the handguard retainer can be slid forward.

DSC_0303 DSC_0306 DSC_0307 DSC_0308

4.  The lower handguard is then pulled forward and down to be removed.

DSC_0309 DSC_0310 DSC_0311

5.  I am asked regularly about what a ferrule is.  Folks, that black metal cap on the end of the lower is a ferrule.  It protects the end grain of the wood from being split open.  We sell a handguard that can use a ferrule if you like the looks of it plus we sell a version that does not need the ferrule.  It is entirely up to you.  I sometimes use the ferrule to accent whatever color handguard I am working with – for example, Dark Olive Drab to Dark Russian Plum.

DSC_0312

6.  This only applies if you buy one of our handguards that uses the ferrule – you can use your existing ferrule by using a screwdriver to bend the tabs open on the receiver stub and then working the ferrule backward and off the wood lower handguard.  You can then glue it to our’s or even leave it loose.

 

 

 

 

DSC_0320 DSC_0322 DSC_0323

7.  When you install our lower handguard, you reverse the above steps.  We sell optional shims in case you need to tighten the fit.  The example shim here is a special orange material we tested and now we use a special hard black rubber.  You can buy our shims or make your own.  In either case, your goal is to add just enough material to get the retaining lever to turn down firmly and lock up the lower handguard.  Because AKs can vary, you may find that you need to either add or subtract material so take a careful look at your lower retainer and decide which way you need to move before you go sanding, cutting, filing, etc.

DSC_0325

So that’s about it.  The following are photos of the M92 with the new ferrule cut handguards installed.

DSC_0326 DSC_0328

If you’d like to learn more or order our handguards, please visit our online store’s Yugo handguard section at:  http://shop.roninsgrips.com/Yugoslavian_c14.htm

 

Note, the following is a video a fellow did showing how he removes and installs M92 handguards in general.  I think this might help some of you who want to see the steps in more detail:

Installing the CNC Warrior Picatinny Rail Scope Mount for the M92 PAP Pistol

Another great accessory for the Yugo M92 or M85 PAP is the slick picatinny rail kit that CNC Warrior sells.  This thing is a breeze to install and is the best means I have seen for adding an optic to the M92. Because the screws are inserted from the rail side, it is superior to other products that require the screws to come in from underneath the dust cover and risk being hit by the bolt carrier.

All you need is the pistol, a drill and some cutting oil to do the installation.

SAFETY STEP – MAKE SURE THE WEAPON IS UNLOADED.  NEVER ASSUME THAT IT IS – VERIFY IT IS UNLOADED BEFORE YOU BEGIN WORK.

1.  This is the top thick hinge of the M85/M92 dust cover.  See the faint circles?  Those are the spot welds and they are very hard!  Do not drill into them!  The new CNC Warrior mount has four holes and you only need to use two of them.  The reason there is four is so you can pick the best two that get you around/away from the spot welds.  Please note that my rail is only silver because it was a brand new design and they hadn’t applied a finish yet.  If you order one, you will get a black rail!

DSC_0241 DSC_0243

2.  Here you can see my fancy high tech tools.  My Ryobi drill, Tap Magic cutting oil to lubricate the drills and the taps.  Note, you will need to buy a tap handle if you do not have one.  Do not take the short cut of trying to start the tap with a regular socket or open end wrench.  You really want the tap to be firmly held so you can tap the threads at a right angle to the surface of the hinge.  Also, see that little black cylinder?  That is a drill guide that you put into the hole you select to guide the drill bit to the right place on the hinge.  Be sure to use the cutting oil!

DSC_0244 DSC_0245 DSC_0246 DSC_0247 DSC_0248 DSC_0249 DSC_0250 DSC_0255 DSC_0257

3.  As an aside, I blasted the mount and then sprayed on flat black Molyresin and baked it.  You’d never know it came to me unfinished.

DSC_0268 DSC_0269 DSC_0275

4.  After you clean up the chips and are ready to do the final screwing of the mount, be sure to apply Blue Loctite so it does not come loose.

DSC_0276 DSC_0278

That’s it!  The mount is solid and it holds my Vortex Sparc red dot just great.  Note our quick takedown pin to make it easy to remove the cover and get the optic out of the way.

Installing the CNC Warrior M92 Folding Arm Brace – So Sweet!!!!!!

DSC_0023

Next up on the agenda was to install the CNC Warrior folding M92 arm brace.  This thing is wickedly well done and if you get it plus the optional installation kit, just about anyone comfortable with using a drill can do it.

The following is a quick photo of the installation kit – you will need a hand drill and some cutting oil – I like Tap Magic but just about any oil will do vs. running dry and overheating stuff.  You do not want to work harden the sheet metal of the receiver — use cutting oil and keep it cool!

DSC_0211 DSC_0213

SAFETY STEP – MAKE SURE THE WEAPON IS UNLOADED.  NEVER ASSUME THAT IT IS – VERIFY IT IS UNLOADED BEFORE YOU BEGIN WORK.

1.  Make sure your weapon is securely mounted and that you can have ready access to the rear.  The PAP buttstock drill kit has this handy little jig block to help you locate where to drill the small starter hole.

DSC_0214 DSC_0215 DSC_0216 DSC_0217

2.  With the jig in place, put in some cutting oil and drill the hole.  Note, I am just using a plain Ryobi 18volt hand drill.  The big bit is 3/8″ and I think 12 volt or better could do the job.  The small hole will help you locate and drill with the bigger 3/8″ bit.

DSC_0218 DSC_0220 DSC_0222 DSC_0223 DSC_0224

3.  Be sure to read the instructions and the caution to go real slow with the 3/8″ bit because if you try to go fast, your bit is apt to grab and thread straight into the receiver.  If this happens then you can’t drill the hole as the bit is grabbed and goes in like a powered screw with a boatload of torque.  Now, I did make this mistake but I knew how to get out – I grabbed a 3/8″ cobalt end mill, checked it in my drill and cut the big offending tabs right out of the hole.  If you run into this, you would need to either get an end mill bit or try using various Dremel bits to remove what is helf.

DSC_0225 DSC_0228 DSC_0230 DSC_0231

4.  My next steps were to use a deburring tool to make sure I didn’t leave anything nasty and sharp in the hole waiting to cut me!  I also vacuumed out the inside of the pistol and made sure it was clean.

DSC_0232

5.  The folder is connected to the receiver via a threaded block that is inserted into the receiver and you then thread the large allen screw into it.  Be sure to line things up and apply Blue Loctite so it will not come loose over time.

DSC_0234 DSC_0235 DSC_0236 DSC_0238 DSC_0239

 

That’s all there was to it!!  This is a very well done piece of gear guys.  The folder mechanism is solid and the brace feels great either on the shoulder or on the arm plus you can fold it out the way.  Note the quick release sling swivel.  I used one of my Troy swivels – the folder has the hole to use one but it is up to you as to whether you want one or not.

DSC_0272

One last comment – I am keeping the printed copy of the ATF approval letter (that comes with the brace) in my case with the M92 to show anyone who asks that the brace is not a buttstock and this the M92 is not a SBR.  You might want to do the same.

By the way, for any of you wondering why I am using all these CNC Warrior parts on this build – the answer is simple – they make really good stuff and this is my personal M92.  I only want solid reliable stuff on it.

Removing the M92 PAP Muzzle Cap and Installing the Detent Pin

The M92 PAP pistol is brought in neutered with a muzzle cap and no detent spring.  With some careful Dremel work, some cold blue solution and a bit of patience, it is really easy to restore the pistol back to it’s original threaded muzzle state

SAFETY STEP – MAKE SURE THE WEAPON IS UNLOADED.  NEVER ASSUME THAT IT IS – VERIFY IT IS UNLOADED BEFORE YOU BEGIN WORK.

1.  Look at the muzzle of the PAP
M92 and you will see a big spot weld that is holding the muzzle cover on.  Thankfully it is both small and superficial so it can be cut through.

DSC_0005 DSC_0008

2.  Now the first step is to secure the pistol so it can’t move around.  I used a wood jawed woodworking vice but you can use whatever you have handy.  If you use a regular vise, be sure to put something over the jaws to protect your M92 from getting all scratched up.

 

DSC_0274

3.  I use my Dremel tool all the time.  These days I am using one of their cordless jobs with two Lithium batteries and I like the EZ Lock bits that make replacing cutting wheels and other tasks a breeze.  Be sure to practice with your Dremel before doing this.  Please don’t go buy a Dremel and try and do this fresh out of the box.  The secret is to make light cuts and not rush.  Let the weight of the tool do the work and carefully guide it and keep it in position.

DSC_0061 DSC_0150

4.  Now, I came in from the front and at a slight angle to protect the front sight & gas block combo.  The cap will twist off clock-wise as it is reverse threaded.  Cut a bit and test, cut a bit and test over and over.  If you have a strap wrench or a pipe wrench, that can help with the removal.  Again, remember that this is reverse threaded just like other AKs.  It will loosen by turning clockwise.

DSC_0067  DSC_0066DSC_0069

5.  Hidden under that large ugly cap is the big 26 x 1.5mm LH (reverse threaded) muzzle just waiting to have your favorite brake or fake can installed but it would be real cool to get the detent pin working again – wouldn’t it?

DSC_0073 DSC_0074

5.  Use a small sanding drum and smooth the block where the weld was and then use the cold bluing solution you like to color the steel while it is fresh and oil free.  I like Brownell’s Oxpho Blue and apply it with a Q-Tip per their instructions.

DSC_0084 DSC_0089 DSC_0090 DSC_0094

6.  CNC Warrior sells a very small kit with the detent pin, spring and cross pin.  The PAP has all the holes there already.  You literally slide in the pin and spring, turn it the right way and then drive in the cross pin, which is a small roll pin.

DSC_0102 DSC_0105

7.  I really like the Bulgarian 4 piece Krink brakes and CNC Warrior has great version they have made for the M92.  I pretty much knew I had to go with this brake!  It does a great job reducing muzzle flash and is real high quality.  Now that the detent pin was installed, I just threaded it on until it was where I wanted it and the detent pin engaged fully.

DSC_0119 DSC_0120 DSC_0123DSC_0121 DSC_0191

So that’s all it took!  I hope this helps you with your project.

Stay tuned for more blog posts about the M92.

How to Install a Yugo M85 or M92 Dust Cover Quick Takedown Pin from Ronin’s Grips

Years ago, I bought a barreled M92 kit from AK-Builder.com and assembled it.  I then installed a Stormwerkz rail and a Primary Arms M4-style red dot and the dust cover being attached to the rear sight block really got annoying fast.  After some careful examination, I figured out a quick release pin with a ball bearing detent to hold it in place would really make things easier.  It worked great and I have been selling the pins like crazy for almost two years.  I made a mistake though – I didn’t take step by step photos about how to do the installation and people keep asking for a how-to guide.  Thus, I recently bought a Yugo M92 PAP pistol imported by Century Arms from my good friend Scott Igert, who owns Modern Antique Firearms in Benton Harbor, MI, so that I could do some step by step how-to instructions with a lot of photos for folks.

The work will be done with a Dremel tool with a cut off wheel, a few small punches, hammer and a rubber gunsmith block.

SAFETY STEP – MAKE SURE THE WEAPON IS UNLOADED.  NEVER ASSUME THAT IT IS – VERIFY IT IS UNLOADED BEFORE YOU BEGIN WORK.

1.  Look at the hinge pin/rivet.  On the side opposite the charging handle, you will see a big rivet head.  On the right side, you will see an odd looking head it is actually the rivet just slightly peened over into a concave washer.  It is that side that we will grind the peened over portion off with our Dremel.  By the way, it is really a pin but it has one end peened over like a rivet.  A rivet would swell into the hole and lock everything up – a pin does not.

DSC_0140 DSC_0143

2.  If you don’t use a Dremel tool, take a few minutes and do some practice cutting with a cut off wheel.  It has a tendency to scoot around and you need to get a feel for it so you can control it.  Please, please, please – do not take your Dremel out of the box and try to do this for the very first time.  I like the cordless Dremel as I can work anywhere and lately I have become very fond of the EZ Lock bits.  Of course you can use whatever tool you are comfortable with but this step by step explanation should make the work required more clear (I hope).

DSC_0061 DSC_0150

3.  If you are still learning, put a couple of pieces of tape with a slit over the pin’s head that is peened into the washer.  With some tape in place, if your hand slips you will be less likely to mar your finish.  Folks, the secret tip is to do very light cuts.  Let the weight of the tool or even less do the work.  Do NOT push down hard or you will snap the bit.  I also rest my hands on any surface that I can to have more control.  You’ll notice I have a rubber gunsmith block to support the pistol – you could use a piece of pine, a hockey puck, or another non-marring surface.  You want the weapon to be stable when you work on it and you will need to lightly tape the hinge pin/rivet free once the head is ground off.  I used pieces of wood for years and years before bought the block – the key is to have the support and use something that will not scratch up your finish.

DSC_0146  DSC_0151 DSC_0152 DSC_0158

4.  You are just removing enough metal get get rid of a small lip on the rivet.  The next two photos show you the slightly concave look I put in the rivet and you can barely see the shaft.  I then used a small pin punch and a tap from a small hammer to get the pin moving.  It will take very little force to get it to move.  If it doesn’t readily move, then you may need to grind it a bit more.  The only thing holding that rivet shaft in place is the peened edge – it is not swollen in the hole.

DSC_0161 DSC_0162 DSC_0163

5.  This is a photo of the removed rivet and the hinge rivet/pin starting to slide backwards.  I then used a small punch pin to push it out.  The fourth photo shows the original pin and washer so you can see the end result.

DSC_0165 DSC_0166 DSC_0167 DSC_0169

6.  At this point, the dust cover hole is clear but do not try to push the new pin in.  The cover cams shut and it will be needlessly difficult to push the pin in.  For comparison, our pin is shown next to the original.  The pin with a groove in it is something you do not want to lose!  The angled portion is face up towards the dust cover and the round end goes towards the gas tube.  When the dust cover closes, the pin slides forward and holds the gas tube is locked in place.  It’s very simple and does the job just fine.  This locking pin is held in the rear block by the dust cover pin so every time you remove the pin, it can come out.  Just keep track of it each time you clean your M85 / M92 as you will need it.

DSC_0172 DSC_0173 DSC_0177 DSC_0182

7.  Now, to install our quick takedown pin, install the dust cover, lift it up and align the holes.  At this point, there is no pressure and our pin will slide easily into the hole.  When the dust cover is closed, the resulting pressures lock everything in place.  That is why it works so well with hinge mounted picatinny rails.  My favorite these days is the hinge mounted frail from CNC Warrior by way and we’ll right up an installation guide for that as well.

DSC_0183 DSC_0185 DSC_0186 DSC_0188

So that’s it!  Again, the key is to use light pressure when grinding the peened over portion of the original hinge pin/rivet away. Then, install the new pin with the dust cover open so it can readily slide in.

Tools That Can Help You Do the M92 Upgrades

In doing this M92, I wanted to use tools that many guys already have or can get without spending a fortune.  I could have used my mill or drill press but I wanted you to see that some simple hand tools are all you need.  The follow are what I used and certainly you can use other tools that work for you.

Dremel Tool with cutoff wheel, abrasive wheel and sanding drum
If you do much gun work, you’ll find a rotary tool to be a huge time saver when used properly.  I have an ancient corded Dremel tool made for Sears plus an 18volt cordless that I use all the time.  You will need some thin cut off wheels for metal, a small abrasive wheel (if you want or do it all with the sanding drum) and a sanding drum.  Because I use my Dremel a lot, I buy the discounted multibit packs when I find them.

Here are the tools at Amazon:

Dremel 8220-1/28 12-Volt Max Cordless Rotary Tool

 

One thing I would recommend against is buying cheap no-name import bits – they often fall apart or dull real fast.  For the last few years, I have been buying Dremel brand bits off Amazon.  Everything you’ll need is in the below accessory pack:

The one thing I will say here is to practice before you try to actually work on your new pistol.  I can’t stress this enough – please practice first!! A Dremel can scoot around and chew things up if your hands aren’t supported and you don’t know the “feel” of how to cut things.  So please be sure to do some testing and practice before you go near your pistol.  I’ve been using a Dremel for almost 30 years (literally) and I still get surprised from time to time but I know what to do to minimize bad things from resulting due to my experience.

Hand Drill
You just need a plain jane hand drill.  It could be corded or cordless.  Slower is better to avoid heat build up.  You will need to drill a 3/8″ hole for the arm brace and a #21 hole for the picatinny rail screws.  All the work I did was done with my Ryobi 1/2″ 18volt hand drill that I bought from Home Depot and have gotten a ton of use from over the years.

Tap Handle
If you do not have one already, go get a tap handle from your local hardware store.  You will need it to get a good square grip on the #10 tap if you install the CNC Warrior picatinny rail.  Some guys try to go cheap and use a small wrench but the problem is that you will have a very hard time starting the threading squarely.  Spend a few bucks and get a tap handle.

Good Vise
It really pays to have a good vise.  There are so many options out there but make sure it is secure and that if it has steel jaws, that they are padded with leather, wood, plastic or something else that is relatively soft to protect the finish.  It could be a tool vise or even one of the rifle cleaning and maintenance vises such as Tipton’s.  Just make sure that whatever you use is firmly holding the rifle and can’t slide as you drill.   You could drill it into your work bench or use some clamps on the corners.

Tipton Best Gun Vise

I specifically used one of my woodworking vises that is permanently attached to my work bench for this project.  It is like the following and you must add wood to make the actual jaws hence the screw holes in the side plates of the vise:

Roll Pin Punches
You could use any punch set but I like pin punches as they have a dimple in the face that goes into the roll spring to help center and drive it.  Note, I have watched guys skip using a punch and just tap in the roll pin with a small hammer directly.  The roll pin punches help but are not mandatory.

I’ll skip the photo 🙂  You just need something to tap the pin punch with.

Cutting Oil

In a pinch you can use regular oil but I like to use Tap Magic for lubricating drill buts and also taps.  This helps them run cooler and last longer

Cold Blue Solution and QTips

My favorite cold blue is Oxpho Blue liquid from Brownell’s.  There are a lot of other brands out there and guys have told me they like the cold blue solution from Birchwood Casey as well.

Deburring tool or Sandpaper

The last tool I would recommend is a deburring tool.  It is very handy for clearing drilled holes of burs.  I used it after I drilled the rear of the receiver for example.

The next posts will be about doing the actual work – I promise 🙂

CNC Warrior Brake and Replacement Detent Pin for the Zastava M92 PAP

To be imported, the M92 has a muzzle nut, or muzzle cap, installed over the threads with a single big weld.  It’s obvious where the weld is and guess what?  It can be easily removed and if you look close that will also then clear the detent spring hole as well.

There are a few brake options out there for the M92.  Bear in mind that like many Yugo rifles, the designers made the size and thread of the M92’s muzzle unique.  It is left-hand 26mm wide with a 1.5mm pitch thread – definitely an oddball.   At any rate, CNC Warrior makes a four piece Bulgarian style brake that really cuts down on muzzle flash that I have been drooling over for a while plus they make a number of other brakes, adapters and fake cans that can fit that thread.

The following are more detailed photos for you.  By pulling the small locking wire down, the end cap can be unscrewed and the brake disassembled into its four parts – the body, cap, cone and spring.

They also sell a detent pin kit so you can have the original method to retain the brake as well and it can be installed in literally less than five minutes because the PAP comes with all the holes drilled:
