Default Part No. 1 The Barrel

Ok Lets Get The Barrel Ready

What your going to do here is get the Barrel ready. By far this takes the most time on an M92 Build. * Don't think that because you got a Brand Spankin New Barrel it is going to Just Push In cause life just isn't that simple and you paid less for a Virgin Kit.


Also some here know just because a barrel has a hole in it doesn't mean the outside diameter is concentric

And by the same token just because the barrel and trunnion were in the same box Does Not Mean You Can Just Push Them Together with No Problems.

Ok now you have to measure your trunnion and your barrel. This one came with the barrel about .005 over at .9055. Too much meat to push in a trunnion weighing in at an even .900. So the barrel had to loose .003 for a .0025 fit at a Dia. of .9025.

You can't do this with a Dremel or in a Drill Press and your going to have to do it on a lathe and Between Centers.

You are also going to have to make the Barrel Face Cuts *With A Mill and relieve the bottom of the chamber to facilitate a positive feed angle. When you have this done you will have to square up the barrel face.

While you have the barrel in the lathe again Between Centers *(Note) Better To Use A Live Center Here) so you won't FU the muzzle crown. Measure and do the muzzle Dia. for the Ft. Sight Base. Also your going to want to do the Hand Guard Retainer Dia. * You want just enough fit here so the HG Cap slides relatively free with no binding. And don't forget the rear sight base and use .0025 here again by measuring both.

The Gas Hole

A Number 28 Drill Bit But Start The Hole With A Centering Drill fits perfectly into the bottom of the Ft. Sight Base from the bottom and this is what you want to use. You want to be On The Money Here Guys and finding the exact center is a must. I use my own method of marking the position of the hole by scribing a circular mark on the barrel not over the exact center of the hole but to let me know just how far to push the Ft. Sight base on. The shadows looking down the hole on the bottom of the FTB can be misleading and I like to give myself some wiggle room. Use the Centering Drill to Chamfer The Hole Just A Bit Also.This should keep you busy for a few days *** Take Your Time Here*** and if your wondering just where your Barrel Pin Hole goes check out the pics this is measured from the center of the Trunnion Rivet Hole and we'll get back to that in Part No. 2

Default Drilling The Barrel Pin * Part 2

After you headspace the barrel you are ready to drill the Barrel Retaining Pin Hole. Make sure of your headspace and drill with a Dummy Rd. the exact length as a Live Rd. so nothing moves.

Start With A Centering Drill Again. Switch out to a Cobalt (I) Bit and use plenty of oil. Now Ream with a 7mm again using plenty of oil.

Keep the hole clean while drilling and again Drill Slow And Use Tons Of Oil

Now your are ready to try a new round to check for a nice Lock Up.

There you Go Now Have A Beer.

Some folks will tell you to drill after riveting but I have found it much easier to do before and just push out the barrel for riveting when you have all your pin holes done for all the other parts that go on the barrel.

And you can see why $625.00 is a fair price to build a Virgin M92 Krink

Set 2 Barrel Pin Drilling

Default Rear Trunnion Milling And Drilling Part 3

Now you have to get the Rear Trunnion ready to rivet.

*You were smart enough to get a Demilled Rear Receiver Stub. If not you will have to come up with one or use a NDS receiver to scribe rour Rear Trunnion so you can Mill And Drill.

Again go slow and use alot of cutting oil when milling the trunnions as they can be very hard metal. Test fit and you are done with this part of the Virgin M92 Build. Next I show you a Quick And Dirty Way to do your Wood.

Milling For The Hand Guard Retainer

You will want to be On The Money Here and I guess you could do this with a Round File if you are careful.

Wood Prep And Finish Quick And Dirty

Me and Wood know each other although we are not what you could call Close Friends I like to make things simple and have found that if you can sand off Gruber # 1's Fingerprints who packed your Kit. You only have now to contend with Gruber No. 2's Not Putting The Wood in a Plastic Bag so it would not get oil stains on it before you received it and it touched Oily Parts.

So some sanding is in order followed by some Steel Wool. * Note I have found the perfect applicator for putting on stain see pic 2. Your wife or girlfriend will know of a Beauty Supply Store and you can find the Foam Wedgies there.

I apply 2 coats of the Military Stain Shown * (Brownell's Has This Stain) in the Pic letting each dry for 18-24 Hrs. I hit the HG's after they are dry with Steel Wool again and then apply a heavy Coat of KiWi Neutral Shoe Polish and letting it dry for several hours. Buff and your are done with this step.

Finishing Up To Riveting


You are almost home now and you just have to Drill And Ream your Rear Sight Base and your Front Sight Base/Flash Hider Mount.

Measure and make sure of the positions of the rear sight base and that your Front Sight Base is going to accommodate your Gas Tube/Upper Handgard.

After you drill and ream your Front Sight Base push in one of your pins to keep everything square for hole number 2.

*Note I use a 5mm pin for the top cover pivot as the supplied small pin is a very hard part to come by and a 5mm Trigger Or Hammer Pin are a dime a dozen just drill with a Centering Drill to bevel the edges so they can be flared to secure the top cover.

All the rest is just like building any other AK

Here Are Some Tips

Use Quality Cobalt Drill Bits

Drill Slow With Plenty Of Oil

Ream All Your Holes *Again Plenty Of Oil

Make Sure Your Handguard Retainer Is On And Facing The Right Way Before Pushing On Your Muzzle Brake

Double Check Your Measurements Before Drilling









Hope This Helped Those With M92 Virgin Kits Wanting To Do Their Build.

Holy crap!

JOHN DESRVES HIS OWN FORUM!!!

Lets lose one of the DEAD vendor forums and make room for these most excellent posts.

Wait, John isn't alone. Gunplumber has contributed too.

There needs to be a seperate HOW IT'S DONE...STICKY ONLY...forum that can preserve all of this valuable information instead of letting it vanish in this forum.

Scott I wish you would have done the wood segment. As I said Wood and I are just Passing Friends and a Woody Expert could have done a Much Better Job than I.

Lex the right tool absolutely helps with a Virgin

Not to be a Smart Ass but did you ever think of measuring the Rollover Pin yourself like I had to do.

This Tutorial Post was for those who want to think and build themselves and not to be confused with a Hand Out.

I'm not getting on Your Shit Man but I darn near told you everything you need to know to DIY

It took you longer to post your rant than it would have to just give the answer.

Rest assured I will no longer post questions in any of YOUR threads. If you see any future posts by me (no matter how stupid you think they are) just ignore them cause they will not be directed at you. As a matter of fact just add me to your ignore list.

Thanks,

great tutorial.

One thing that might help those who don't have a demilled receiver section to use for machining the stock axle hole, is to get a 3 degree angle block. Then the receiver can be clamped using a 1-2-3 block and the 3 degree between the jaws of the mill vise and you can machine the hole after the trunion is installed.

I used one size lower carbide inch pattern bit, which left just kissing it with the dremel sanding drum to bring it to the metric diameter.

No Rant Son just trying to get you to use that thing that sits upon your shoulders. How hard is it to measure???? Or for that matter actually go that extra mile and put a rule over the HG Retention Groove of any other AK.

But for those who seem to be challenged when it comes to motivation and initiative. 15/64 Which is .020 shy of 6mm.

Most people doing the virgin build would probably already know this, but, I would NOT use the rails that come in the virgin kits - buy a set of AK builders. The rails that came in my kit were sloted - no need to ask for this kind of trouble.

PM me in a week if you haven't heard from me, cymax. My M92 is in the back of my truck and I'm driving back home after being away for a few months, and I can't measure it right now.
