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!

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!

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.

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.

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.

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.
