Bullboss magazine issues

[z_johnq]

Hello guys, I bought a Bullboss .22 about 10 days ago at about $390 at MidwayUSA. A nice gun, and the power and accuracy are well expected! After about 40 shots, the magazine refused to rotate, occasionally. I checked around at GTA and it looks like I'm not the only one that has the problems. But not sure how to fix it. If I cannot, I will probably return it and get a BT65 for a change (too bad, they are all out of stock).

People say Bullboss side lever cocking is quite smooth, but I like BT65 side bolt better, may not be as smooth as AT44 but never gave me any headache.

A couple of posts mentioned a few screws are too long, which causes the problems. I'm too slow to figure out what screws. Does anyone have a pic of that?

Thanks in advance.
