    The UPS guy delivered my Kral Puncher Breaker Marine Bullpup Tuesday, but I had to work so today was the day to shoot.

    The first 6 mags shot flawless, then after a fill it would not cock completely, I got it to shoot the rest of the mag. Something wasn’t right. I pulled the stock off and cleaned the bolt area thinking I got dirt or something in it. Still not right. Then I noticed that the nut on the linkage from the trigger to the sear was really loose and turned easily. It looked like a locknut but it didn’t seem to have the nylon part that locknut’s have. So I took it off an tapped it with a hammer to flatten it a little so it had some friction when I re-installed it. When I installed it I decided to take all the slack out of the linkage. I reinstalled the stock and had the same problem, WTF? I took it apart about 3 times before I figured it out. The linkage has to have enough slack in it because the stock pushes up on the linkage taking up the slack. If you take all the slack out and then try to install the stock it won’t let the sear catch the bolt when you cock it. I’ll take the stock off tomorrow and get some pictures.

    So is the problem fixed after taking care of the lock nut?

    Yes, that fixed it.  While I was in there, I lubed the bolt with some moly and cleaned the hammer area.  The gun is very simple.  It is a lot like Benjamin.

    As you can see in the middle picture the rod is curved, as the stock pushes on it, so the nut has to be loose enough to not pull on the sear.

    Not the best design.  What was happening was the nut was so easy to turn that the vibrations from firing the rifle would tighten up the nut and cause the hammer not to be caught by the sear.

    Is it possible to cut a groove in the stock for clearance so the rod doesn’t touch?
