Yugo AK Jamming - Help!

[22HM77]

Finally got a chance to take out my new Yugo AK, which was a lot of fun, despite the jamming. Anyways, my guess it that the mags are the culprit, but I'll let you decide:

The rifle seemed to function fine when the mags had 5 or less rounds in them (30 round Yugo mags that came with the gun). Any more than 5 would cause stoppages sometimes as often as every other round. These stoppages occurred as the bolt slammed forward on a half-fed round i.e. the round was at a 45 degree angle coming out of the mag when the bolt hit it (about halfway between the shoulder and the base of the cartridge).

I think its the mags because:
1. The stoppages seemed to correlate with the number of rounds in the mag.
2. One mag seemed to feed better than the other.
3. Both Wolf and Golden Tiger 7.62x39 were used to equal success/failure.

But alas, I am a newbie when it comes to diagnosing stoppages. What do you think is the problem, and how can I fix it?

I would recommend trying the original style magazine(the short 10 round one). A vast majority of extended mags seem to have a problem feeding into the gun.

i had the same problem with mine, for some odd reason, one of my mag doesn't like silver-bear ammo, but it works great with all other brand, i recommend that you:

1. disassemble the mag and clean any cosmoline, grease, or anothing that make it sticky.

2. check the mag body, it may be bend, causing the bullets to get stock

3. just get another mag and test if it works (or buy a new one)

+1 on the magazine. Does it feed perfectly with the magazine that came with the rifle?

FWIW I tend to put a strip of duct tape on the bottom of ANY new magazine I buy and make a tick mark anytime I experience jams while shooting it. I can then pretty quickly eliminate any "bad" magazines from my collection.

Just my .02

What kind of receiver is this gun built on? If it is a NoDak Spud receiver check and clean your magazines. If this gun was built by a "home gunsmith" on a NoDak receiver from one of the Centerfire parts kits you may have other issues.

I have one of the Century built Yugos and a second one built by Red Jacket, both are good guns.

the mag latch is improperly set, its allowing the mag to sit too low and causes the bolt to only strip rounds from the left side of the mag reliably, its a very common problem for first time AK builders... the fix can be simple or it can be a PITA depending on your abilities as what needs to happen is to remove a very little material from the selector stop (ya can see where its milled already under the mag latch.. thats to adjust mag height) and then after the height is set correctly ya will need to build up the mag latch and fit it so the mag is held tightly against that milled section of selector stop..... another area is to adjust the rear of the magwell, without seeing a picture I can not tell ya 100% which area yours needs but in either case the mag latch must be extended to hold the mags tight..

ak-files.com

hit the gunsmithing section, until its fixed correctly it will never function reliably

I'm guessing this is a Century gun? If so, it has a year warranty. Box it up and send it back to them. This is the only way these companies are going to learn to stop shipping crap out the door.

My first Yugo from Century was fine, and the second has been a problem. I had to send the second one back for a canted sight, trigger group issue, and a loose handguard. They returned the rifle with a G2 trigger group which fixed one problem. I haven't shot it yet to see if the canted sight (zero) problem is fixed. As far as the handguard goes they didn't do squat and it still flops around because the front band is bent and they were too lazy to disassemble the gun, remove the front band and replace it. Instead I think it only got a couple whacks with a hammer. Once I shoot the gun to confirm that the canted sight issue is fixed, they are going to get this gun shipped right back to them a second time.

Century has my Yugo UF right now for the same problem you describe. Apparently there have been several Yugo's with problems based on the posts on the other site. Send it back.

 

[22HM77]

How exactly do I send it back? Can I ship the rifle directly to Century, or must I have a FFL do it?

 

[briansmithwins]

When I had problems (canted FSB and floppy mags) with a CAI rifle I contacted the vendor (classicarms.com) that I bought the rifle from. They were great and sent out a prepaid shipping label to return it. They also sent out a hand-picked replacement.

Unless there is some funky state law that prohibits your shipping a firearm for repair, you can do all the shipping yourself.

Before sending it back you may try liberally lubricating the new Yugo. the action on my new Century M70B1 barely dry-cycled without pushing the bolt a little, and many times the bolt would stay in the open position when racking. I disassembled and thoroughly lubricated the Yugo with Tetra Grease and Eezox spray and it has run fine ever since.

trbon, I had the same issue with handguard wobble and I fixed it pretty easily. This is only a cosmetic problem that doesn't affect shooting the gun, although it can get annoying.

This is what I did. I removed the handguard and looked where the loose points were which were allowing it to wobble. I then added some JBweld to these points and let it dry for a day. Then I sat for about a half and hour and filed down the JBWeld until the handguard fit snugly. Now there is no wobble and I didn't have to send it back.

Try this out, I'm sure that it will work and it will be a little easier on your gun that hammering away.

 

[trbon8r]

Picard, that is a good idea. I still think the front band on my gun needs to be massaged a little bit. The bottom of the band is noticeably bent out and allows the handguard to move. I'm going to try and see about using a torch to heat the band enough to bend it back some. Your idea about the JB Weld is a good idea for final fitting once I get the band bent back enough to where it looks halfway straight. Thanks!

Before I do anything though I need to shoot the rifle and make sure the zero problem has been fixed. If not the gun will need to go back to Century a second time regardless.
