Aero Precision M5E1 Handguard BAR Barrel Nut Kit DPMS Thread for AR-308

Aero Precision M5E1 Handguard BAR Barrel Nut Kit Features This barrel nut kit is specifically designed to work with Aero Precision's M5E1 Enhanced upper receivers. The BAR (Barrel nut and Rail) interface system simplifies installation by allowing handguards to mount directly to the barrel nut using a sturdy 8-screw interface. This ensures a secure anti-rotation setup with no need for complex alignment tools or timing. The included DPMS thread pitch supports compatibility with most standard .308 AR barrels. The nut itself is CNC-machined from hardened steel for durability under high torque and extended firing schedules. Aero Precision's design provides excellent barrel-to-receiver fit aiding in improved accuracy retention across multiple sessions. Whether upgrading your upper assembly or completing a new build this barrel nut kit is the required foundation for enhanced handguard attachment in the M5E1 ecosystem.
