16" 5.56 NATO AR-15 Upper Assembly | 1x8 Parkerized Carbine M4 Barrel | Flash Hider | 15" MLOK Rail
Far from being just a basic configuration, the 5.56 NATO is the definitive, battle-proven standard for the AR-15 platform that balances high-velocity performance with unmatched versatility. This system thrives with a massive variety of ammunition, specifically tuned for 55gr to 77gr loads to provide unrivaled reliability across tactical and sporting applications. If you're building a dedicated duty rifle or a high-volume range trainer, a 5.56 upper assembly offers the widespread parts availability and flat-shooting consistency required to push the limits of the small-bore gas gun.
Ballistic Barn 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.

556 upper
Great deal on this upper and it is actually really good quality. So far 1.5" groups with silver bear ammo but I suspect it will tighten up with quality american made ammo. Shipped quick and was well protected.

Just what I needed and a great price. Upgraded to the FDE furniture and it looks VERY sharp. It likes 55 gr AAC vmax ammo!
