Default trouble with AK feeding ammo

Got a WASR 10/63 that keeps getting ammo stuck while shooting. Sometimes goes 8 rounds, sometimes goes 2, but then it jams. Just the tip of the bullet gets in the chamber and then it gets stuck. Also getting marks and scratches on the bullet and sometimes a little dent on the case.

Could it be a mag problem? Just got the gun, cleaned it before using, but there is a problem somewhere.

Where do I start?

The mag's looks real rough and has sharp edges on top, I was thinking of smoothing it down in the top of the mag.
2 Metal 10 round mag's by the way.

Any advice greatly appreciated. I know my way around a SKS, but the AK platform is new to me.

interestingly enough, i had the same issue with my AK last time I went out using what looks like old metal mags. Not sure of the make. The springs seemed a little soft and when feeding the magazine, the rounds would shift such that I would have to reposition them to stay in the correct double stack orientation.

I was using standard wolf/tul/brown bear stuff (not sure which one i was using at the same).

needless to say, when i went to tapco (yea....tapco) and circle 10 mags, i had no feeding issues.

those two mags are now out of commission (i might try it again to see if i can recreate the issue) and I will stick with tapco/circle10/bulgarian steel mags that are blocked OR arsenal/tapco 10rd mags.

Get a WASR...wait sorry, that's my standard AK thread reply. I'd try different mags, maybe a stubby 10 rounder. I've noticed on one of the 10/30 steel mags I have the spring gets hung up on the riviting. This doesn't happen in my 25+year old pre-bans.

See where the bullet is leaving copper marks if possible (on the ramp) and then with a dremel, felt tip and polishing compound, hit that area.

Also check the length of the ejector, this can lead to all kinds of problems in the AK. (It's somewhat counter intuitive, but in addition to ejecting the empty casings the ejector plays a part in guiding the bolt as it picks up a fresh round.)

- Field strip
- Put the bolt & carrier back in and observe how well the ejector fills the gap in the bolt. If the bolt has a lot of play as it passes next to the ejector, that may be your issue. You want the ejector to fill out the gap while not binding.

Specs to check: (measure from outside of receiver to ejector tip)
AK47: 0.560
AK74: 0.580

Try different ammo, try different magazines, let it break in, return if needed...I am a dremel guy but will not ever tell anyone to use it.

Just throwing this out there, but is it the bolt carrier that stops midway on the rails? Do you then push the charging handle forward and it feeds correctly, or does it jam that you have to clear it, eject the round?

Additionally, what ammo were you using, hollow points or soft points can be a big problem with some AKs.

Do not start dremeling anything just yet.

Here's an interesting thread that recently popped up that might help you in possibly IDing the issue, as in the mag is sitting too low. Also some good pics for reference.

If it is just the bolt carrier stopping midway on the rails, you may simply have to de-burr the rails, which is basically sanding them very lightly, specifically in rough areas. DO NOT sand your ejector. I had to do this on my DRACO. Or just shoot a couple of hundred rounds, that usually does the trick.

No, I cant push the handle forward as the round is stuck in their. The tip of the bullet, about 1/4 to 1/2 inch is in the barrel but the round is sitting at an angle and has to be cleared out of the gun before anything will move.
Also, looks like the bolt is hitting the side of the cartridge, not the end of the round.

I am using WPA (wolf) FMJ ammo, no hollow points or soft points

try the obvious first, find somebody with mags that you know 100% work. Then try those.
Then feed ramp, then bolt extractor etc etc etc

Well, read through the link I posted, mags could be sitting too low, symptomatic with some WASRs.

Also follow sd_shooter's words of advice and do some measurements, as well as, MrPlink's, start with the basics again, eliminate the mags.

"eliminate the mags", as in, hopefully you know someone with some reliable mags that can be tested against the mags you have used.

Default You can try that without going to the range

you should be able to take the dust cover off, insert the magazine with a couple of snap caps and see if it sits too low. You can insert the other magazines you have and compare. Or even cycle a few rounds through by hand with the dust cover off and the recoil spring removed so that you can see exactly what happens.

I dont have any snap caps for this gun. If I cycle it by hand, with the cover and spring off, would it work with a empty shell casing? Normally I would never put a live round in a gun and cycle it at home, I just believe in always being safe.

Shell casing wont work. The bullet itself is what initially slides on the feed ramp into the chamber and without that you are more than likely to induce a malfunction of some sort. On a different note some folks will intentionally randomly load just a case into a mag to practice failure drills while at the range.
