I got me a Yugo m70 ab2 that has been messing up, it will double fire randomly with one trigger pull, then it will hit the next round lightly and cause it to not fire.

I spent a goddamn pretty penny on this rifle and I want to use it safely! So if anybody has any ideas, or if they need pictures (or video) let me know, any help will make me a happy little tatortot!

Thanks!

Is the rifle running away? Meaning you pull trigger and some times it fires until the magazine is empty? When was the last time it was cleaned, a good cleaning can fix a lot of things?

 

[acidlittle]

nope it's just a 2 round burst, it's never fired more the 2 rounds in one pull

 

[jgriner]

Im no gunsmith, but i would start buy cleaning the bolt assembly, what maybe happening is the firing pin is getting stuck for the first 2 rounds, once you fire the gun the firing pin is sticking forward and it fires again as soon as the bolt closes with its new round. soak the bolt assembly in hopps 9 over night oil and see if that makes a difference.

A malfunctioning firearm is unlawful when it provides more than one round fired per pull of trigger, this part of the batf is fairly lenient. It has a lot to do with did you make your firearm malfunction, are you attempting to repair it, are you working towards getting it repairing it, do you know its malfunctioning. But then again obama is president.

Here is my copy of ak 47 manual.

I did clean the hell outta it, including the bolt and carrier assembly....

I'd have to agree with jgrinder on this one... I'd immediately remove any references to multiple rounds firing with one trigger pull. Even if accidental or inadvertent, it can get you arrested or as a minimum, have your weapon seized (or all weapons seized as they verify that is the only full auto weapon you have).

Please consider this seriously...

After you reword your earlier posts... I'll edit mine so there is no record.

These guys are good, they rebarreled my norinco when it was having issues. They specialize in the AK variants, reasonable prices and great guys to deal with. Talk with Mike he is the gunsmith.

I dont think you need to panic, and i dont think you need to send it off, ak-47 are extremely simple, just some spring, coiled wire used a a spring, piston, bolt assemble, firing pin. I think your fireing pin is jamming, by being dirty.

Take the gun apart, place all metal objects in a pan of hopps 9 let it soak over night, then oil SPARINGLY, reassemble you should be good to go if that doesnt work then talk to a local gun smith/gun store, then ship off as last resort.

I think I'm going to take your advice Jg, gonna soak the shit outta it and clean it until it shines like diamond!

I'd recommend you replace your FCG - Fire Control Group (Trigger, Disconnector, & Hammer) with a Tapco G2.
You might also want to use a Tapco Retaining plate in place of the sheppards hook.

I had Krebs Custom do a trigger job on the Century FCG in my Sar1 back when they still did custom work. The result of their trigger job was a too light trigger that would seemingly double when I was locked down shooting slow fire from the bench. It wasn't FA but actually a shoulder bump fire that was happening. I replaced that FCG with a Tapco G2 and now run G2's in all my AK's.

Some other things to look for:
Is your sheppards hook installed?

If there is a Tapco G2 FCG in there now is the sleeve installed? The sleeve goes over the trigger pin and through the trigger and disconnector.
The G2 wont run right without that sleeve.

Is there a spring under your disconnector? They have been know to be missplaced.

Are the legs of your hammer spring resting on top of the bars of your trigger?

Here's knowledge base on the AK and DIY FCG replacement.
While this site applies to Romanian AK's the tips in here apply to all AK's:
Romanian Kalashnikov Rifles

Here's how to remove your FCG.

Note there is a section on FCG polishing.

I find that polishing an FCG will usually cause what it happening with your rifle and would recommend against it.

Ok, lets start out with i am a professional gunsmith. Not a wannabe. 50+ years exp.

Ak's, regardless of who made them are pretty reliable out of the box, unless someone has dicked with them.

To check, remove mag, safe to fire position, clear weapon, remove top cover, remove spring assembly, remove bolt and oprod.

At this point hammer should be cocked.

While holding front of hammer with one thumb, pull trigger, allow hammer to come of the hooks and move about 15 degrees,

continue to hold trigger in firing position, push hammer rearward till the top of the hammer slides under the disconnect that sits in the middle of the

trigger.

Once it clicks into position, take thumb off. It should hold it in place. If not, check to see if there is actual mechanical engagement (about 1/16" overlap),

at this point release the trigger letting hammer slowly go forward.

Push on the disconnect to see if there is sufficient spring pressure for it to hold the hammer.

You will have to determine if it is the disconnect, hammer, or disconnect spring or any combination of them that have failed.

Sometimes a-holes hack this part or the hammer hooks to make them f.a. They will blow up from out of battery fire.

I send all guns to JoJo's Gunworks for anything beyond my capabilities or if if I'm just to damn lazy to do it myself. Their work is nothing but top notch and deal with customers from around the country on a regular basis. They do have experience with AK's also. They are not just a 1911 shop. Here's a nice piece of their AK handy work.

If nothing happens when you pull the trigger, and there is a light strike on the round that is chambered, you will need to replace your Firecontrol group (trigger and hammer) I believe there have also been some cases of slam fire, because the firing pin floats freely in the bolt it hits the primer lightly every time a round is chambered, If your problem is only with commercial US made ammo and not with Wolf or Tula (or any other steel cased imports) this is a likely culprit. I think someone is making a spring kit for the firing pin but am not certain. I am not a gunsmith, but I have built AKs from parts kits and am familiar with them. If you replace the FCG the Tapco trigger works great, and the retaining clip is easier to deal with than the stock spring.
