    Default New Build Won't Cock Second Round

    I built three new aks. One of them will shoot the first round, and eject, load second round, but the hammer does not cock for the second round. Anyone got any ideas. I can't see any difference between it and my others.

    so when you charge the first round in it feeds that one fine and picks up the second round and the hammer follows the bolt back and isn't cocked?
    Sounds like the hammer may be rubbing on the bolt. Is it hard to charge?
    When you have the bolt to the rear and release does it go forward smoothly or does it feel like its dragging?

    Make sure the carrier is smooth on the rails. With the return spring out the carrier should move very free. IF it is the next thing I would check is making sure your disconnector moves free. If it is "sticky" you might not be catching the sear. Make sure the safety has enough room so the trigger and all parts can move with easy and not hit/bind up.

    Sounds like the disconnected isn't catching the hammer, alowing the hammer to follow the bolt.
    If everything on your rifle is in spec, receiver, axis pin locations, rails, etc., more than likely it is the disconector/spring.

    If you have another FCG, you can switch out the trigger parts one at a time to determine the problem.

    I agree with the above comments
    it sounds like the disconnector I had this problem in january I switched out the disconnector and i was good to go

    as indicated above the rails may also need to be sand papered down abit to remove any burrs

    Thanks for the advise. The hammer is indeed following the bolt. The carrier is a little snug going across the hammer. I did try to slick all that stuff up a little this morning. I will take it back apart and look disconnector and spring over.

    Did you perform a FCG function check to see if there is hammer follow?

    Disregard the receiver type. Here is the function check>

    I had that problem once. Hand cycling worked fine but firing it the hammer would follow, sometimes. My disconector was functioning fine, it needed a microscopic amount of metal removed from the rear top of the hammer shelf where the disconnector catches. On another earlier build that I didnt harden the fcg pin holes the hammer pin hole wallowed out enough to let the hammer ride farther up just enough to not let the disconnector catch.
