Hey all, I am new to the board. Have been a long time M1 Garand, SKS and AK shooter for years. I just picked up my first AR. Other than the M16 I carried for a couple years.
I have an A2 frame. I am interested in the mount that bolts on the carry handle with a thumb screw. Do they work thier way loose while shooting. Plus I would take it off from time to time does that mean re-zero.
