Strongest AR15 BCG XPB Extreme Performance Bolt
The Sharps Rifle Company XPB BCG is presented as a high-performance upgrade for AR-15s, emphasizing its S7 tool steel construction for increased tensile strength and a DLC coating for lubricity and easy cleaning. Its reduced mass design minimizes carrier cant, leading to smoother operation and less wear. The BCG also features a Relia-Bolt with tapered lugs for improved feeding and undergoes rigorous testing, including HPT and MPI.
