This complete upper receiver from Alpha Shooting Sports features a Nitride treated CNC precision-machined barrel chambered to handle 5.56 NATO rounds sixteen inches long. The M16 bolt carrier group is also treated with Nitride and built to withstand the rigors of excessive use with minimal maintenance. The Alpha full-length M-LOK-L handguard is free-floating and extra-light, with ample room for your favorite accessories. Alpha Shooting Sports dimples the barrel to secure a low-profile gas block, and the weight of this upper receiver. This Alpha Shooting Sports fully-assembled upper receiver features a 9310 MPI tested bolt assembly and has extended M4 feed ramps for reliable and consistent magazine operation. Forged from 7075 T6 aerospace-grade aluminum with a Type III Mil-Spec anodized coating, this upper receiver from Alpha Shooting Sports is made from U.S. parts and features a limited lifetime warranty.
