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:

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’s M92 PAP Picatinny Rail Mount is Excellent!

A M92 is screaming for an optic of some type.  My preference is a red dot and I run a Primary Arms M4 clone on my first rifle and will use a Vortex Sparc on this new rifle.

As some of you may know, I have a Stormwerkz rail on my first M92 that I custom built and it has served me well.  The only draw back with the design is that you install the button head screws from inside the dustcover.  Because of this, you will notice the bolt carrier does hit screws.  I have shot a ton of ammo – well over a thousand rounds – from this rifle and the bolt carrier shows no harm but you do see the scuffed screws.

When I heard that CNC Warrior had a mount, I had to take a closer look and sure enough, they had a different approach.  Their screws go through the rail and screw into the thick steel portion of the dust cover that runs to the hinge.

I talked to Denny, the owner of CNC Warrior, about my plans and he recently switched over to a four hole model that will give a person more options when installing the rail to work around the very hard spot welds — basically you just need two screws so with four holes, you pick the two you like that enable you to miss the welds.

If you look closely at the next photo, you will notice small circular indents in the steel – those are the spot welds that are harder than the surrounding steel and can be an absolute bear to drill through.  Thus, with CNC Warrior’s new four hole rail, you can slide it back and forth until you get two holes that clear these welds.

Please note that Denny sent me one of each – the old two hole rail and the new four hole rail – so I could show you folks the difference and he did not have time to have it finished so it is bare metal in the photos.  I used Molyresin to finish it flat black but that is not something you will need to worry about.  Going forward, when you order his mount you’ll get the four hole rail section already finished black.

Included with the picatinny rail is their installation kit and instructions that makes installing it a breeze.  In a future blog post I’ll show you just how easy installation is and how you can do it with a hand drill and some cutting oil.

CNC Warrior Folding Arm Brace for Zastava M92 PAP

One of the parts I knew I wanted was the folding arm brace from CNC Warrior.  This essentially gives you additional support to either fire the pistol with one hand or to even shoulder the weapon comfortably if so desired.

Now the ATF has reviewed and approved the arm brace as not being a shoulder stock.  Each arm brace that CNC Warrior ships includes a copy of the ATF letter that says it is not a stock and that attaching it will not make a pistol a SBR.

This stock is a joint design effort between Chris Bonesteel, of Bonesteel Arms and CNC Warrior and is very nicely made.  It has a very strong hinge mechanism and is a breeze to install.

When I took the assembly out of the box I immediately noticed how well made it was.  I recalled a talk I had several years back with Chris where he worried about some folders being weak and this design reflects that both he and Denny at CNC Warrior wanted to make a strong one.  The attention to detail and fitment are very apparent.  Hands down, this is my favorite set up that I have seen for the M92.

The following are photos of the brace for people who like to see details:

The following photos shows how nice brace marries up to the back of the receiver plus the quick release sling hole but it has not been attached yet.

It comes with the mounting screw you will need and easy to follow instructions:


I highly recommend you buy their installation kit.  It comes with the drill bit and mounting jig to make this a breeze:


In a later blog post, I’ll show you just how easy the installation was. I kid you not, if you have a hand drill and their installation kit, you can do this!!

New Zastava M92 PAP Pistol Arrived – Of Course It Needs to be Modified!!


So the Century M92 PAP pistol arrived from via my friend and FFL, Scott Igert, of Modern Antique Firearms.  The cool thing about this pistol is that it is actually made in the Zastava factory and is imported here.  Zastava originally designed the M92 to be a 7.62x39mm short barreled rifle (SBR) based on the proven Kalashnikov design that could pack a lot of firepower in a small package.  To do this, they gave it a short barrel and an underfolder stock.


To make it legal for importation, Zastava opted to go the pistol designation route with the ATF and thus did not install the underfolder plus they spot welded a muzzle nut over the large 26×1.5mm threaded muzzle.  Because the muzzle nut was spot welded, they didn’t bother installing the detent pin either.

After getting mine out of the box, I have to tell you that I am very impressed by the quality.  This is my second Zastava AK – my first was a Yugo M77 – and both are very well made.

This pistol has received a lot of good attention over the last few years because of its reliability and heritage but it also got negative marks for its weight and being unweildy.  Really?  I always found those comments funny because of course you are trying to hold a  stripped down SBR that weighs about 5.7 pounds empty with one hand!

Now the fun part.  The whole reason I am writing this blog post is because these pistols are still available at a reasonable price and there is a very active aftermarket including the grips, handguards and dust cover pin that we make.  We’ll have a series of blog posts to step you through how to install the various parts we selected including some wicked parts from CNC Warrior.

Time permitting you will see a few blog posts each week that step you through what I bought, tools and installation.
