With anywhere from 5 to 7 rounds left in the magazine my VEPR K .223 will eject the next LIVE round out with the spent brass from the shot just fired. Then the bolt closes on an empty chamber.

I have no idea how this is happening or what is the cause. It happens with a variety of magazines and occurs about 50% of the time with any given magazine.

Nothing looks out of whack to my untrained eye. It has been this way since I got the rifle over a year ago. I was hoping the problem would go away on its own.  No such luck.

My usual ammo is XM193 or Q3131A.

What say the AK gurus?

Definately sounds like a mag issue.  When the bolt moves back, the next round must hop up and jump the feed lips.  I've played around with some 7.62x39 in M16 mags and they do the same thing.  Are you using 5.45 mags for the 5.56 ammo?  If so, that might be part of the problem.  You could try using some Galil orlites and see if those helps any.  If it isn't the mag, I don't know what could be causing it.  Odd.

... With a half loaded mag, give it a fairly smart rap to the floor-plate on a piece of wood (opposite the direction you would load into mag well).

... If the cartridges fly out, it's almost certainly a magazine feeding lip problem

I fired 120 rounds today rotating 2 Bulgarian waffles and a RobArms modified AK74 mag every 10 rounds.

I got one malfunction with a Bulgarian mag. When the third to last shot was fired the second to last round flew out also, leaving an empty chamber and one round left in the magazine.

That's all for now.

Well, I hate to say it

but 223 in an AK platform is a crap shoot when it comes to mags.

no standard 223 mag means... no standard!


see if you can narrow it down between the Bulgy and Robarms mags.  Robarms uses a special follower and a 5.45 mag system and should work reliably in their own gun.
IIRC, the Bulgy 223 mags (and rifles) are built on an AK-47 pattern guns, as opposed to the newer AK-74.  The '47 guns have a slightly wider mag well, so the mags are a bit wider.  But if they are made for 223, the feed lips should be shaped correctly...

I dunno.  I'm just thinking out loud...

Galil 5.56 mags don't count as standard?

no, although they may be the best to use in a Galil.

The 223 AK is a frankenstein gun.  Some countries modified the obsolete AK-47 AKM platform for use with a 223, like the Bulgarians, and some others used the newer AK-74 platform as the basis for their 223, like Russia, (east Germany?) and others (Chineese? Israel? South Africa?) created their own or I just don't know where they fall.  The geometry of the mag well and mag interface is different depending on the pattern used.

The question is what kind of pattern your rifle uses and then finding mags to match that pattern, or grinding something to make them match.

The VEPR is built on an RPK receiver.
