Have a look at Bravo Company Manufacturing (BCM)? I am pleased with mine and am able to get ~one inch groups at 50 yards with iron sights (I cannot see further than that with my tired old eyes) using Federal 62 grain FMJ ball ammo.x007x wrote:Yes you are right about brownells..I'll do a recheck on the items again. The reason I got that gas block..Ok i was using ar15builder.com and when i chose other gas blocks, they were uneven with the upper receiver and were lower. For the gas tube, yeah i just realized i didnt have that. I am accepting all adivce from everyone. I have looked at a completed upper but wasn't finding what I liked.
Best of luck with your build and look forward to seeing pictures when completed!
