Ive brought this up before and need to bring it up again before I proceed.  I read in a book which list's/identifies AK's that a model of the Hungarian AMD 65 was produced that can be identified by grey handles and a shim thats pinned from the bottom of the chamber that has a threaded barrel on the trunnion block end so that granades could be launched from it.  I have tried several types and several times to use a pully puller to separate the barrel and trunnion to no avail.....it will not move.  Is it at all possible that it could be threaded.....I would try to turn it out but want to avoid slipping the site block forward if it is not necessary to attempt to turn the barrel out of the trunnion....thank you for all the help you can offer..........Mike.

It shouldnt be threaded its probably just in there real tight. Im assuming that you removed the barrel pin

Grenades are launched from the muzzle. No stamped AKs have threaded trunnions unless something rare has been eluding me all these years.

Maybe you were thinking of the AMR-69?

That link is awesome, it isnt what I was referring too however, Im fairly certain the book specified Hunagarian AMD 65.  Ive looked closely at the barrel and trunnion and I dont see any hint of thread.  I think the book may have just confused things......I will wait to see if I get any more replies and move forward with having the barrel pressed out on a hydrolic machine....thank you for your responses, Barrel pin is removed from the trunnion block and site block, I dont think it would work to launch grenade from the trunnion end of the barrel...I too suggest using the muzzle......Mike.

I've built a couple AMD-65 the only threaded part on the barrel is where you put the muzzle brake.
Whoever said the barrel threads on is wrong its push and pin

If you are trying to pull the barrel you have taken the barrel pin out first right?

Ive taken the pin out........thing will not budge.......looks like brute force will have to sufice....

I always thought it was called an AMP 69? At least that's what the books say...

Put the barrel and trunnion on a hydrolic press today......broke/bent the press cross beam.......dude.......this sucks.  The barrel pin is pulled out.....under the trunnion block is an obvious pen thats ground off really well that appears to hold the shim in place on the inside bottom of the trunnion block......it does not appear to a part/attached to the barrel.........is it?  We have access to a HUGE hydrolic wood plitter.....Im going to use some angle iron thats longer than the barrel and set it up...Im sure something will give........or break......unless someone has a better idea...Im open to suggestions.

Pictures, please.

Ok get out the gasoline and matches, Have you considered bucking the rivets against the barell?

I wouldn't do this under normal circumstances but in your case.....

Is anyone who has an AMD 65 familiar with the shim in the bottom of the front trunnion block?  Is it attached to the barrel in anyway?  Ive pulled the barrel pin and cannot get the barrel to press out using a hydrolic press, the cross beam on the press bent.  I dont think in looking at the trunnion block, that the shim, which is obviously pinned from the bottom of the trunnion, is in anyway attached to the barrel however the barrel will not move at all.  We are going to try and set it up on a wood splitter to press the barrel out however Im concerned something else will give if Ive missed anything.....really.....it seems pretty easy and I dont feel Ive missed anything...any ideas?
