Polymer80 Glock Build Troubleshooting

If you haven’t heard about Polymer80, they make a number of 80% receivers including some remarkable Glock compatible frames. Now they aren’t just a cheap gimmick – I like the grip angle, the texture and the finger relief that all result in a far better feeling pistol than an actual Glock in my opinion. Now there are haters that say these are not Glocks – that’s fine, they aren’t. Then again, it’s not like we all buy ARs only made by Colt or Armalite either in comparison.

So I have been posting about how to do the builds [Click here for a Glock 17 using the PF940V2 frame post and here for one on Glock 19 using the PF940C frame post]. They are very straight forward, fun and can generate a reliable pistol. Like all things, there can be challenges and troubleshooting your build to understand why the slide is binding, the trigger isn’t resetting and so forth are all things that may happen. Luckily, there are also lots of videos and posts for understanding how to solve the challenges.

Be Sure to Read the Instructions First

I do recommend you read the instructions from Polymer80 before you do your build. If you didn’t read them and are now having challenges, I would recommend you go back and read the good instruction file they wrote and watch the video:

Troubleshooting Videos



Also, Pew Pew Tactical did a nice series of posts on building and troubleshooting Polymer80 builds. Click here to open a new tab and go there.

My Take On Common Issues

  • The slide doesn’t go all the way back: Check that the recoil spring is not catching on the channel you needed to mill out. Check that the slide stop spring is sitting flush and not catching on the spring. Sometimes plastic falls into that channel and keeps it from fully seating. (It would be a good idea to blow your frame out with compressed air to get all the loose plastic out).
  • Trigger not resetting – this is either an issue with how Polymer80 did some of the Rear Rail Modules (RRMs) or how the frame was drilled causing the RRM to move. If this happens, you will need to file a bit off the right side (when looking down at the receiver) of the RRM so the trigger bar doesn’t hit it. I’d also recommend checking that there aren’t burs/machining imperfections on any of the trigger’s metal parts that might cause binding.
  • Slide not cycling smoothly – The rail modules should be equal height. Again, there may have been an issue with drilling causing an alignment issue. See if you can bend/adjust the rail modules so they line up.
  • Trigger feels gritty – remove the trigger and polish all metal surfaces. Blow out the pistol and trigger areas to ensure there isn’t any plastic debris. Expect it to take a couple hundred rounds to smooth out.
  • Action feels gritting – again, polish everything. I like the small rubberized polishing bits for the Dremel as well as working with sandpaper up to 2000 grit. Always remember that your goal is to smooth and polish, not to remove a ton of material.

So, I hope this helps you out. Polymer80 Glock frames are well engineered and do work. There may be some issues you need to work through due to how you build the pistol and the parts you use but view overcoming them as part of your journey and don’t give up. The end result is definitely work it.

Two Videos On Preparing Polymer80 PF940C Glock 19 Frames For Use

If you haven’t heard about Polymer80, they have come out with a really straight forward way to make a pistol using Glock parts. You aren’t going to really save money but you are going to have a very cool end result that you can customize however you want.

In surfing around, I came across two videos that have some pretty good camera angles and commentary about guys drilling the holes and filing down the frames that I thought I would share:


Polymer80 is offering some really innovative products. These are not hacks by any means. I like the grip angle, the texture and the finger groove built into the trigger guard. The whole concept is well executed for guys who like building their own firearms.

Note, Polymer80 products are being sold by a ton of vendors so shop around and watch for sales.

Also, be sure to download and read their instructions. They are well illustrated and have pretty good detail.

Great video on Doing a Polymer 80 Pf940V2 Glock Build

In the previous post, I told you about my finding Gunstreamer for firearms videos. What brought me there was that I was searching on Google for Polymer80 build videos.

On Gunstreamer I found this great video of a guy, who is obviously experienced in building Glock pistols, showing a build on a Polymer 80 Pf940V2 80% frame. He steps you through what needs to be done in terms of sanding, filing and drilling with the supplied jig and then he goes on to actually assembling the pistol.

I learned a lot watching the video – he has a solid informative style and shows you what he is doing.

Here’s the Video

Check out Gunstreamer for Firearms Videos

Folks, if you are like me and are sick and tired of the assault by liberals on our second amendment freedoms, you are always looking for sources of firearms advice. Youtube used to be a great source for videos on firearms – everything from reviews, to gunsmithing to build-it-yourself (BIY) guidance. Unfortunately, that is no longer the case – Youtube has turned anti-gun also and I resent it.

So, where can you see videos about firearms? One promising source is Gunstreamer – http://www.gunstreamer.com. I’ve watched a few videos there now and find the site easy to navigate and there are definitely some quality videos showing up there. Definitely check them out and consider supporting them – I am.

Midwest Industries’ 9.25″ AR Combat Series Rail is Slick!

I recently was looking for a free floating handguard for a 10.5″ AR pistol build and happened upon the new Midwest Industries (MI) Combat rail series. The name made me think mall ninja but the design is interesting and they did a good job manufacturing the assembly.

The 9.25″ M-LOK Combat rail looked good and three things caught my eye – the barrel nut was knurled, they had an innovative means of timing the handguard to the receiver, and it looked good. Yeah, looks do matter to me.

This is the 9.25″ MI Combat rail as it arrived. I have that small tub of barrel nut grease ready.

So,I availed on Holiday sales and ordered one from Optics Planet. The handguard arrives with everything inside. In other words, you need to unscrew the lower two clamping screws to then remove the barrel nut.

The first hint this is different from a lot of handguard that simply clamp is that insert in the middle – that’s the indexing key.
Here is the knurled barrel nut, the indexing key and the two screws.

Now you may be wondering why I care about the design of the barrel nut. There are two reasons – first, the knurling creates a more anti-slip surface than a smooth surface would. Second, and perhaps more importantly, the groove that the key rides in allows the rail to align any way you need it to with the receiver without having to deal with shims and it inhibits the rail from sliding forward. Combine thee knurling, key and very generous tabs that position the rail on the receiver and this rail is very well retained. In other words, it isn’t going anywhere unlike many rails that shoot loose and all of a sudden you are holding the rail separate from the weapon because it slid off the barrel nut. That’s not going to happen with the Combat rail.

Installation Video From MI

MI took the time to assemble a short video for you to understand what is required to install the rail. It’s very straight forward.

My Installation Tips

To be honest, I read the paper instructions that came with the rail and realized it would really help to see what was needed so I watched the above video. I really do recommend you take just under 10 minutes to learn from them first hand. That’s tip #1 🙂

Tip #2 – I’d recommend you use a Magpul Barrel ExtensionVise Block – a “BEV Block”. You need to apply quite a bit of torque to remove the existing nut and 40 foot pounds to install the Combat barrel nut. Click here for a post that provides more details.

Tip #3 – When you remove the muzzle device and/or existing barrel nut, I’d recommend you use open end wrenches and NOT an adjustable wrench. Countless millions of nuts and muzzle devices have been marred or destroyed by adjustable wrench jaws giving too much and rounding corners.

I have a big SAW combination set that I use for tasks like this. For example, to remove the PSA barrel nut that was previously installed, I used this big 1-1/8″ wrench and it took quite a bit of torque to break it free. Again, use a BEV Block or Giessele Reaction Rod to safely handle the torque.

Tip #3 – do degrease the parts. You never know what was used during manufacturing or by a previous installer. For example, my PSA barrel nut was lubricated by some white colored grease. I have no idea what is was and used denatured alcohol to remove it from the receiver plus cleaned the new barrel nut.

Tip #4 – Do use Mil-Spec barrel nut grease. It is designed for the appplication and prevents the nut from sticking/corroding onto the upper receiver.

Tip #5 – Do use a torque wrench to install the handguard. I used to do “farmer tight” where you bring something up firm and call it even. The problem with that is either you apply too little torque and the nut loosens up or too much and you strip the threads. MI supplies the appropriate fitting for a 1/2″ torque wrench. The spec calls for 40 foot pounds so do it.


If you don’t have a 1/2″ torque wrench, there are good deals on Tekton wrenches at Amazon. Just be sure to reset the scale to zero before you store it.

Tip #6 – for the same reason as the troque wrench, use a torque screw driver to install the gas tube (if it uses them and torque will be 25 inch pounds or there abouts) and the handguard’s Allen screws require 55 inch pounds.

I use a Vortex torquing screw driver for optics. It only goes up to 50 inch pounds so I installed the handguard screws to 50 and not 55. There are other screwdrivers that go higher but that is what I had handy.

The Wheeler FAT torquing screw driver can go up to 65 inch pounds. I have one and it works – I just don’t keep it on my bench now that I have the Vortex.

In Summary

I’m very pleased. The rail is rock soild and looks great on my pistol.

How to Safely Change AR Muzzle Devices and Barrel Nuts Using a Magpul BEV Block

If you like working on AR-type rifles and plan to replace a muzzle device or change a barrel nut to install a free-floating handguard or to swap barrels, you are going to need to apply a lot of torque. Torque and aluminum are not friends and this is certainly the case with the upper receiver for AR rifles and pistols.

What not to do?

I actually want to take a minute and tell you two things not to do. First, do not simply clamp your lower in a vise and go cranking on whatever on the upper. Remember that the upper is connected to the lower by two steel pins going through relatively soft aluminim. Not a good combination.

Number two, there are work fixtures that look like a rectangle that allow you to remove the upper from the lower and then pin the upper to this block that is then held by a vise. I’m not fond of this either because then your two aluminum connection points on the receiver take up all the stress and they weren’t designed to do so.

Please do not do either of those or you may regret it. The odds are that you will regret it. I word it this way because you may get by once or twice but these methods are risky so don’t do them.

So what do I recommend?

At this point, it comes down to two options that engage the barrel extension, which can handle the torque of any AR upper operation you may need to perform. The first is the Geisselle Reaction Rod. It’s pricey but it does the job and you can get a relatively good price on an AR tool kit from them on Amazon.

The second approach, which is what I use, is to secure the upper in a vise using a Magpul Barrel Extension Vise (BEV) block. It’s a very well designed block that engages via the barrel extension with its own steel lugs that are designed for strength but also to not harm the extension.

This is the top of the BEV block. You can see the front engagement lugs, the rear protrusion is for the bolt carrier and I would recommend keeping that O-ring oiled. The hole just under the front lugs is for a cross pin to secure it to the upper.

The BEV block uses a bolt carrier with the bolt removed to further secure it in the upper. You could remove the bolt from the bolt you normally use. I have a bolt carrier body that I keep in my toolbox for just this purpose.

The following photo shows it partially inserted in the upper.

This next photo shows it fully forward with the bolt carrier assembly installed. It does not have a cross pin installed at that point. Even without the pin it can handle the rotation stress. The pin just keeps it all in position and is not load bearing.

At this point you are good to go to change muzzle devices, barrel nuts or whatever else you may need to do without risking damage caused by torque. It’s a solid tool and I highly recommend it.

Great 1/2×28 Thread Protectors for Rifles and Pistols

It’s very common to have pistols and rifles with threaded muzzles. A very common thread pattern for .22, .204, .223/5.56 and even some 9mms is 1/2×28. This means the thread is 1/2″ wide and has 28 threads per inch (TPI). This is the most common pattern for AR rifles for example as .223/5.56 rifles tend to follow the original military specification thread pattern. There are many patterns out there so you always want to confirm. For a variety of reasons, you may not want to install a muzzle device. If this is the case, I would recommend installing a thread protector, sometimes called a “muzzle nut” to protect the threads. For example, here is a 10.5″ AR pistol upper receiver assembly. You can see the 1/2×28 thread and I did not plan on installing a muzzle device. 10.5″ upper with a 9.25″ Midwest Industries Combat M-Lok handguard being installed. This is going on an AR pistol in Michigan, which has an odd law that pistols must be under 26″ overall. It will use a muzzle nut to safely stay under the limit. Thread protectors simply screw onto the end of the barrel. The only thing I do is to apply some Blue-Loctite to reduce the odds of the nut rattling off. Yes, the heat of the barrel will soften the Loctite but the “gummy” nature of it will do the job. If you plan on taking the thread protector off and putting it back on a lot, then don’t use a thread locker. On Amazon, there is a very good deal on US made thread protectors. They are made in the USA with excellent machining and a phospahate finish. The photo at the top and this next photo show the thread protector installed on an AR pistol. 10.5″ AR pistol with barrel nut installed and SB Tactical collapsing PDW style brace. I hope this helps you out. The Amazon listing is the product I used on the above build and really like.

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.

PTR PDWR In The Leaves

The lighting was right, the leaves were on the ground and it was a great chance to get some new photos of my PTR 105 PDWR pistol.  This big pistol is the interesting brain child of PTR.  It’s essentially a cut down HK 91.

The PTR 105 configuration has a PTR metal handguard installed.  After messing with it some, I decided to install an MP5 handguard as I like the angle on the MP5 handguard more.  This also means I should have just bought the PTR 110 that comes with that handguard.

Now, the only problem is that the MP5 handguard is not as rigid as I would like.  I’ll experiment some with different handguards in the future.

The PTR 195 and 110 are big pistols at 23.5″ overall, 8.5″ barrels and weigh about 8 pounds.  I wanted to install a brace but needed to be mindful of Michigan’s odd 26″ maximum pistol length law.  This isn’t legal advice, but my understanding is that the Michigan State Police say that a pistol with a brace is measured from one end to the other in the minimum operable condition.  So, by installing a side folder, I could have a brace for when I wanted to use it but also had the minimum operable length at 23″.  What you see in the photo is an SB Tactical BTFA folding mechanism, buffer tube and SOB stock.  When open, the weapon measures 32.5″. 

Thanks to the BTFA folding mechanism, I can swing the SOB brace to the left and it locks open.  This keeps the brace out of the way of the ejection port.  You can configure the BTFA to go either left or right.
It definitely has clean lines.
The PDWR definitely likes the PPU battle packs of .308 FMJBT 145 grain ammo.  It works great and is plenty accurate within 100 yards.  I’ll need to try and shoot the PDWR for accuracy some day and see what it can do.

As you can see, the brace is folded open and operating side of the PDWR is nice and clear of any obstructions.

Given the PDWR is chambered in .308 and uses 20 round HK G3 magazines, that is a lot of firepower in a small package.  Overkill?  Sure.  Fun at the range?  Absolutely.
