The AR-15 5.56/.223 Wylde 18" Black Claw Premium Upper Assembly combines accuracy, aesthetics, and durability into a high-performance platform for the serious AR builder. Featuring an 18" 416R stainless steel HBAR barrel with double-color spiral flutes, this upper is chambered in .223 Wylde, offering peak precision with both 5.56 NATO and .223 Rem ammunition.
The mid-length gas system balances smooth cycling and recoil control. A competition-style muzzle brake tames muzzle rise and flash, making this a go-to setup for range, duty, or DMR-style builds.
Finished in a black hardcoat anodized 7075-T6 forged receiver, paired with a 15" slim-profile free-floating M-LOK handguard, this upper provides ample space for optics and accessories without compromising balance.
