are these rifles really worth the price? someone mentioned a problem with extracting cases earlier, i have seen this problem on another M1A, but it would easily extract, you just had to do it manually, the rifle was essentially brand new. on anther M1A i saw recently, it looked like the rounds were being fed too "high' they would run into the top of the receiver and hold the bolt open, i think it was factory 175gr or something like that. do these rifles just require alot of fine tuning? or are they very sensitive to ammo? or.....are they just junk?.... i dont think i have any use for a rifle that is that sensitive.
