I might have an opportunity to sort through a collection of AR-15's and pick out a few to buy at a very reasonable price. I want get a couple of 6.8 SPC's. There are 15 of these in the collection and while I haven't seen them, I've seen pictures and descriptions. The two I'm looking hardest at both have left-side ejection. I'm pretty ignorant of this mechanism though and while I know that Bear Creek Arsenal's left side charging system is reciprocating, I understand many are not. I'd prefer not to have that handle move upon firing. How can one tell if it is reciprocating or not without firing it?
Also, given a choice between a YHM 16" Fluted Fluted 1:11 twist and a AR Performance 16" Fluted barrel, all else being equal, which one would you choose to increase the probability of getting a superbly accurate barrel (recognizing that a little experimenting in ammo selection may be needed)? I've heard good things about both manufacturers.
