  • Sgt of Arms AR-15 15.5"ARCA Handguard

    This handguard is one of the most versatile handguards on the market. It has full M-Lok capabilities on both sides and the bottom but also has a full ARCA Swiss Rail on the bottom. The ARCA rail is great for locking into a tripod or being able to move your bipod to any point on the handguard without adding extra picatinny rail sections to your handguard. These are compatible with the Aero M4E1 Enhanced upper receivers or regular receivers with a bar barrel nut. This rail is perfect for the tripod hunter or PRS shooter wanting to get the most out of their equipment.
