I'm switching out the AR style stock mount for a pic rail mount. The lower screw came out easily; the other one is not cooperating.





I've got two Allen keys that are also twisted. I got the bit driver so I could try tapping it with a hammer while turning it.  Anyone else have this issue? Would taking the tube off help at all?


Edit: Got it out. Heated it with a grill lighter, let it sit then more hammering.

New question. Do these threads look crossed?
