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!

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.

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.

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.

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.

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.

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.

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.

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!!
