I have had good luck with Bushmaster AR15s. They seem better then the service rifles I carried. I have an Armalite AR10 as well. It seems pretty nice. Gonna work up some target loads for it this summer and I hope to see 1 MOA. We’ll see. I have seen a bushmaster xm15e2s (Bushmaster’s standard AR15) with a trigger job and a nikon scope shoot about .25 moa incidentally (it might have been closer to .223 moa-hole for hole actually).
I’ve seen a lot of people praise Bushmaster...
