My friend and I have Vepr fm AK47 rifles. I bought 5 surplus polish mags and he bought yugos from AIM surplus. We shot them today, and only 3 of my mags feed, and only 2 of the yugos. The bad mags failed in both rifles the same way. They will only feed from one side or the other. The yugos and 2 of the polish mags will jam a round fed from the left side of the mag, and one polish does the right. Any idea what will fix this. Stoppage was the same every time.

Ive only used one East German and one AIM Poland mag with my Vepr FM but haven't had any problems.
Did you try more than one kind of ammo? Sounds super unlikely but maybe the ammo is weak and both guns are short stroking? Also on the Yugo mags make sure you got all the cosmoline out of the insides cuz it will slow down the feeding of the mag, super sticky stuff. EDIT: Actually really look at the short stroking...why would it grab the shell right after the rim when the rim is sitting a hair higher or even? Make me think short stroking even more. Good luck with it and let us know the resolution! |
| The mags aren't sitting high enough in the gun. When I've seen this issue in the past, it's usually the selector stop plate that hasn't been milled enough on the underside to allow the magazine lug to sit at the right height. I'd try more mags, but it could be a rifle issue. |

I believe this to be true. They mags already have a little up and down play, so it will need a new catch and everything. Depends. If you hold the mag tightly does the bottom of the bolt strip a round with authority when you hand cycle (meaning, is the bottom face of the bolt hitting enough of the round in the mag to reliably strip it)? If not it could be that your selector stop is the problem. If it is, replacing the mag catch alone may not be a sufficient fix. From what I see unless you build AK's or know someone who's good it should be returned for a replacement / warranty work. Given that it's a new gun, I would recommend sending it back. Do make sure that it's not the mags by testing it with at least some Bulgarian ones, but it appears to have slipped past qc from first glance. Good luck, sorry this happened. |

The kicker is, FIME customer service told me that they can only gaurentee function with a Molot magazine. I don't know how true that actually is, but it sounds like I can pay to ship them my rifle and a hand full of mags, and they will only test with new Molot mags. The rifle works fine with every polymer mag I give it, but it's so hot or miss with steel so far, I just don't have confidence in it. I have some new in wrapper Hungarian and polish mags coming, so I'll re evaluate sendingnit in after I play with these. Luckily, there's a couple good smiths in the Nashville area, so worst case, I'll just end up throwing some money at it. |
| Time to break out the dial/digital caliper and start taking some measurements. About the only way to for sure run a problem like this down with any certainty, then go from there once problem has been positively ID'ed. Could be a thing where the mag height is set to ONLY work with the Molot mags to insure they sell the only mags to reliably work with that rifle. Should be able to fix it though you may have to remove the TG/mag catch to do it, PITA though. Are the Molot mags single or double stack mags ?? Some AKs have a single stack bolt which doesn't work well with double stack mags after conversion, unless you swap for a standard double stack bolt. The difference is the width of the bottom part of the bolt that strips the round from the mag. Single stack bolt is more narrow causing issues with a double stack mags. |

So it works fine with some mags, but not all mags. Sounds like a mag issue to me. Mark the bad mags, or just throw them out. Problem solved ;) Normally I would say the same thing, but multiple mags from different countries of origin having problems, it sounds more like a rifle issue. |

Also, what are the odds AIM sends me nothing but bad mags? |

The problem is in the rifle. Something is off, sounds like either the mag catch or possibly even the front lug contact area sits too low, maybe both. The fact that the OP can push the mag upwards and it works pretty much explains it. In any case, it's not as difficult a fix as some are making it out to be. If the mag catch sits a hair too low, tig a little material on the top of the catch itself. If the front sits too low, basically a similar fix. It's an AK, not a supercomputer that requires a professional with arcane knowledge of some sort. |

Lol. I need an arcane AK wizzard. I wouldn't be mad at all if a WASR or a kit build needed a little metal added to work right, but that's the reason I bought a $1k Vepr. Don't blame you a bit, I would be agged too. FIME refusing to warranty unless Molot mags are used??? Boy, that's some K-var type crap right there. Sorry you have to deal with it man, but what I suggested will likely work for ya. I guess the mighty slantback Vepr continues it's reign as the King. |

Unfortunately I would not expect FIME to correct the issue if it really is the selector stop plate. As others have mentioned it's probably either the plate is too thick, or the mag latch has too much material removed from it. Either way the back of the mag is sitting too low when feeding.
If you pull back on the bottom of the mag while shooting, it should seat the rear of the mag as high as it will go. If this corrects the issue, you may need to replace the latch. If the issue persists, the selector stop plate is probably too thick and will need to be removed, ground a bit, tested, and riveted again. You may also be able to grind the shelf on the selector plate carefully without having to remove the entire TG assembly. There is a small shelf where the mag tab rests against the selector stop plate, which is milled a tiny bit from the factory. This will allow the mags to seat a bit higher, but if there is play in the rear of the mag, they will still droop down, and either the latch will need to be replaced with a virgin latch (most are ground a bit at the factory) or the entire selector stop plate removed and thinned, which moves the entire TG and latch assembly up. If you want to do this but are concerned about redoing the rivets on your own, the AK Builder trigger guard screw plate is an excellent piece for adjusting selector stop plates, and will allow you temporarily affix the trigger guard without riveting to make adjustment and testing possible. If you stake the screws to the plate internally, it becomes a semi-permanent installation. I have done two AK builds with this piece just because I didn't have a jig for the front TG rivets. Using recessed hex head cap screws and staked internally, there are zero issues. |

Why should I not expect FIME to fix an expensive rifle? With myself and my friend, and this guy makes 3. It's a legit issue. Attached File |
