So I took my dremel and ground off my A2 gasblock/sight on my barrel, since the stupid taper pins wouldnt move for me. Well, 2 grind wheels later, it was gone, and i stuck one of those flip up sights/gas block things on there. Pretty damn sweet. shot it today, worked like a charm. not one single problem, the whole day. put 120 rnds downrange, not a hitch. was a blast to shoot! Now, just waiting for whatever assclown admin clerk is working my paperwork to hurry up and run my info so i can get my damned re-enlistment bonus, and start padding certain vendors bank accounts! wheeeeeeeeeee!
