This is the do-everything 300 Blackout build: a 16" chrome moly barrel with 1:8 twist and a medium profile that balances weight against heat dissipation for extended range sessions. The pistol-length gas system keeps cycling reliable across both subsonic and supersonic loads, and the full 15" MLOK rail gives you room to mount a suppressor, foregrip, and optics without crowding the barrel nut.
AR15 Elite brand uppers are American Made and machined by manufacturers of mil-spec AR-15 components. All barrels are individually checked for headspace using Manson go and no-go gauges.

16 inch upper
Nice little upper and it's lighter than expected which is nice. Only did a cycle test so far and it spits out in the same spot every time. Head spaced it myself with PTG gauges and it checked out perfect with their BCG.

300 BO upper
Excellent upper. Got it dialed in 100 yards and got 1.5 inch groups with PSA AAC vmax ammo. Tightened up nicely with Hornady Black to 1" or slightly less. Accurate.

Just what I needed
Cycles, shoots and performs well. You'll be happy. Oh and don't be cheap on your ears, get the linear comp. You're welcome.
