How to remove the Zastava M92 PAP Pistol’s Factory Thread Cover

A few folks have asked how to remove the factory installed thread protector from their M92 PAP pistols.  Zastava does actually thread the pistols and it’s a 26mm diameter x 1.5mm pitch left hand thread (M27x1.5LH is the short cut way to write it) under that cover. These things were installed for importation, ruin the look of the pistol and, fortunately, are very easy to remove if you take your time.

Now I used a Dremel with a cut off wheel.  You could just as easily use a hand file.  For me, I used the thread cover to protect the threads and did not worry if it got scratched.  Cut a little and try to turn the thread cover.  It will turn clockwise to be removed once the weld is broken.  Note, if you decide to use a Dremel and are new to them, practice with your cut off wheel on some scrap metal before doing your pistol.  They can hop around unless you know how to hold and maneuver them.

I prefer cordless Dremels with removable batteries so I can swap them at any time but any rotary tool will work. You’ll need at least an abrasive cutting disc to cut through the small spot weld.
I couldn’t take the photo and cut but you go slow with the cutting disc and only remove enough weld for the thread protector to freely turn.
Not a very clear photo but you can see the remaining weld on the thread protector.
Here’s the remaining weld on the front block. Note, don’t toss your thread protector as you can use it to safeguard your threads as you grind down the remaining weld.

   

Next, I put the thread protector back on and used a stone wheel in the Dremel to clean up the remains of the weld on the gas block.  Again, if you are new, practice first.  The stone wheel may look simple but they can make a mess real fast if you lose control.  I’ve been using Dremels since 1985 – trust me when I say you should practice first.  Also, I like Dremels and have used them for years.  They have tons of corded and cordless models plus there are other rotary tools on the market if you expect to have very limited use and want to save money.

I used a small stone and light pressure to remove the rest of the weld. Putting the thread protector back on will keep you from damaging the threads. Grinding wheels like to hop around if you aren’t very careful.
While the steel is shiny and clean, use your favorite cold blue to stain the steel. I like Brownell’s Oxpho-Blue liquid.
Burnish it with steel wool, repeat and apply oil.
Done. By the way, you can get the M92 muzzle break detent assembly from CNC Warrior – they actually make them.
Here it is again with better lighting,

I hope this helps you out!

Check out Fred’s Wicked PAP with Our Lower Handguard

Fred’s PAP looks sweet.  He’s using both our lower handguard and one of our quick takedown pins.

Scott Igert’s Custom Yugo M92 PAP with Dark Russian Plum Furniture

Scott Igert owns Modern Antique Firearms in Benton Harbor, MI, and is the force behind the Michigan Gun Exchange website.  He replaced the furniture on the below Yugo M92 PAP:

The grip is our ARM9 (which is my favorite grip by the way and use it on my own rifles) and he used a Yugo M92 Ferrule Cut furniture set for the handguards.  Both are in our Dark Russian Plum color with a blasted finish for good looks and a sure grip.  I also like the contrast between the black ferrule and the color of the handguards – I think that is a nice accent.

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:

 

Dremel 710-05 160 Piece Accessory Kit

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:

IRWIN 226361 6-1/2-Inch Woodworkers 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:

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!!

 

Note, I have to buy all of my parts – nothing here was paid for by sponsors, etc. I do make a small amount if you click on an ad and buy something but that is it. You’re getting my real opinion on stuff.
