Light Primer Strikes

I have been experiencing light primer strikes w/ a converted Saiga.

I ran a box of Winchester 7.62x39 through it w/o issue. This is not the case w/ Wolf black box and their Military spec ammunition.

I'm thinking it's due to the hammer spring.

Any suggestions?

I have the same issue on a cheap-o M+M M10-762 with Tapco G2 trigger. I'd like to get some ideas on fixes.

The Russian ammo has harder primers than US made ammo.
Replacing the hammer spring would be a fine place to start since they are really cheap and easy to replace.

How old is the Saiga? How does the firing pin look?

Yes, exactly why I came to the conclusion that it was probably a weak spring issue.

Firing pin is GTG. Checked it against another that has been 100%.

I have no idea on age as I purchased it used. Like most firearms it looked almost untouched when I picked it up. It's a shame people never really shoot their firearms.

It's a great rifle when it functions. No AR but it's quite accurate and makes 100 yard hits on steel w/ ease using an H1 4moa. I want to run it through a class when it is able to run reliably.

Could I bend the springs to get me by until I can order new ones? If so how would I perform this? I'm not really up to speed on AKs.

I'll purchase the M10 from you if you'd like to pawn it off on someone.

Not sure how well bending it would work, but it's worth a shot. I would remove the spring and then bend forward the portion that pushes against the back of the hammer and then reinstall it.

I am going to throw out there that it is odd for a hammer spring to give out, they are extremely durable, but it is worth a try since it would be a simple fix if it is the problem.

K-Var sells Bulgarian ones for like $8 iirc.
Damage Industries sells US made ones for $7, but I cannot vouch for their quality.

So what else could it be causing light primer strikes? There's not a whole lot going on inside of this thing.

Maybe the firing pin is jacked, could be flattened out in the back or front, though you said that you already checked that and it's good. Or maybe if the face of the hammer is messed up.

I am no AK smith, so not really sure what else could cause it.

Might try soaking the bolt in a cleaning solvant and getting a can of air to blow any gunk in it out. Dunno if that's the problem in your ak bit I've seen that I. SKSs before.

For future reference, the first two numbers of a saiga are the year manufactured.

Make sure the hammer is hitting the back of the bolt flush. Sometimes the hammer is mis-formed and hits the bolt at an angle, or off center. I don't think ammo would cause this though.

Would knowing the date of manufacture make a difference ?

It is not the ammunition. It runs fine in the other AKs and VZ58.

If the hammer isn't striking true what can be done to remedy the problem?

Replace the hammer. Generally a pretty cheap component, can normally be had for under $10.

I saw the same thing happen to a guy that installed his hammer spring incorrectly in a norinco. He made it work...some of the time. He was convinced the rifle was junk. I told him a Chinese kalish was a great rifle. We corrected it then it ran flawlessly.

I wouldn't bend the hammer spring. I was posting the photo to make sure you have it positioned the right way. Some people will put the legs of the spring beside the trigger, instead of on top of it.

I have done conversions on two Saiga and I have never heard of them not running 100% with Russian ammo. AK guns are robust and don't light strike. They fire ammo with hard or recessed primers well.

My bet is..

(1) that when you moved the fire control group forward,
(2)you some how have the hammer or hammer springs installed incorrectly.
(3)the trigger pin is not been held in place correctly by the shepards crook or plate, whatever you are using.(or not using)
