Sons of Liberty Gun Works SCALPER Bolt Carrier Group – AR-15/M16

The SOLGW SCALPER Bolt Carrier Group is a mil-spec BCG designed for reliable function in AR-15 and M16 pattern rifles. Built to USGI specifications, this BCG serves as a direct replacement for factory groups or as a spare for shooters who demand proven performance. The SCALPER name reflects SOLGW's commitment to combat-proven designs that prioritize function over flash.

Manufactured from Carpenter 158 steel with proper heat treatment and shot-peened for durability, the bolt is MPI (Magnetic Particle Inspected) and HPT (High Pressure Tested) to ensure structural integrity. The carrier features a phosphate finish for corrosion resistance and proper lubricity. Gas key is secured with Grade 8 fasteners and properly staked. This is a drop-in component, though function testing and headspace verification with your specific barrel and upper receiver is always recommended.
