    Feeding issues

    My M70 Milled Yugo will strip the first round out of the mag then maybe the second then nothing until I eject a round.
    Then it will fire the next round and again maybe one or two rounds or maybe not at all.
    The mags are going in all the way it appears I may modify a few mags and take a bit off the top and see what happens.
    I would rather take it off the mag than the receiver.

    Could be the recoil spring. Might as well get a hammer spring too.

    Could be. I'll get some springs and try that.
    I'm going out today and see how my mag mods worked.

    Is your gas tube locked down all the way? Maybe the piston is dragging?

    Took the recoil spring out and while I did wipe it off when I first cleaned the rifle I did not look real close at it.
    Took it apart last night and it was covered in what looked like burned on cosmoline.
    It was a sticky black tar like substance so I figured that was my cycling issue.
    The sticky goo was not letting the spring rods operate as quick as it should have.
    I did find a wad of that burned cosmoline up inside of the bolt carrier where the spring operates.
    Cleaned all that crap off by scraping and soaking in hot water then spraying with goo gone to get the last of it off.
    Haven't shot it yet to see if that fixes the issue but I am betting that was the problem.
    Cycling the gun manually is smooth as glass now.

    That is a strange place for overheated cosmolene.
    Constantly studying spots welds, mag well dimple shapes, center support rivet heads and selector markings for the last 12 years...

    BTW - Keep your BFH away from my AK!

    WTB Late East German 7.62 top cover and gas tube numbered 687.

    I agree I have never encountered that is any AK I have ever had.
    Sure the old brown cosmoline you find in parts kits but this smelled similar but black like tar and sticky as all get out.

    It sounds like you are experiencing short stroking. Your description is not very complete.

    When the rifle will not fire the second round is there an empty in the chamber, empty chamber or a new round chambered?
    Is the hammer cocked or did it fail to reset? and then you must cycle the carrier to chamber a new round and set/cock the hammer?
    Have you completed a FCG function check?
    Have you tried different ammunition types?

    AK FCG Function Check

    1. To determine if your chosen AK type fire control group is working properly
    2. remove the magazine
    3. pull the carrier/bolt to the rear and make sure the chamber is empty
    4. point the rifle in a safe direction
    5. place the safety in the semiauto "fire" position
    6. pull the trigger normally and hold it to the rear (do not release the trigger)
    7. pull the bolt carrier to the rear and let it go forward on its own power
    8. look to see if the disconnector is retaining the hammer
    9. release the trigger normally
    10. watch to see if the hammer is released by the disconnector, and the primary trigger hook grabs the front of the hammer. The hammer should be cocked at this time if the FCG is operating properly.
    11. repeat the above steps several times
    12. if the hammer doesn't follow the bolt forward, this part of the check is good
    13. next, manually re-cock the hammer
    14. place the safety in the "safe" position
    15. pull the trigger normally, the hammer should not be released by the trigger

    Does not reset during the function check or when firing?
    The FCG may not be the problem as the receiver and/ or axis pin location can be at fault.
    You can observe the disconnector and hammer hook as you perform the FCG test with the receiver cover removed but the recoil assembly in place.
    note if the disconnector pawl/hook., traps/captures the hammer on the rear shelf of the hammer.
    The hammer shelf can be lowered (filed) a bit to allow the disconnector to capture the hammer.

    Does not reset during the function test because the disconnector does not grab the hammer.
    If I push the trigger forward a little the disconnector will engage.and reset.
    I thought maybe the hammer springs weren't putting enough downward force on the back of the trigger.
    I bent them to get more downward force but that didn't fix the resetting problem.
    I'll file a bit and see what happens

    I filed the shelf on the hammer and that fixed the issue.
    I did find a new hammer spring today and installed it as well
    Thanks for the help I do appreciate it.
