Accurate, lightweight, reliable
I bought this to build my wife an AR, and I want one for myself now too. I changed the hand guard to an OD green of the same model for her preference only, but that is the only change. This upper is quite accurate. I've routinely managed sub 1.5-inch groups at 100 yards with a red dot (Vortex Sparc) and IMI 62gr ammunition. Federal 55gr seems just as accurate, though I haven't tested as much yet. The upper has not had a single issue cycling steel cased ammunition (Tula) either. The barrel appears to be a thick profile, which made me assume it'd be a little heavy ... but with the Red Dot optic installed, the weapon is easy to carry for hours at a time. It's definitely NOT heavy! My build worked great with the following components: This upper (duh), Vortex Sparc optic, Anderson stripped lower, BCM PNT Trigger, AR-Stoner parts kit and buffer kit, Magpul MOE collapsible stock, Magpul grip. Buy this upper! (PS, it looks absolutely sick in OD Green too.)
100 yard, IMI 62 Gr, no wind
Looks great in OD Green!
