I can't believe I stayed away from the semi for so long there are so many more parts to play with, my bolt rifles are boring now, just as I got the hang of shooting them this came along, fun, fun, fun.
Take a look at Elfster's threads on the RRA 556's. Especially the ATH. i have 2 RRA's the Elite Comp and the Elite CAR A4 as well as the Colt 6920 and 6921. Both of the RRA's are more accurate than the Colt's and the triggers are much crisper and lighter.The reliability of al 4 have been the same. Not a single problem with any of them. I prefer my RRA's over the COLT's but you won't go wrong wither either.
