This video from Brownells Gun Tech features Caleb Savant demonstrating the installation of the Sons of Liberty Gun Works (SOLGW) M89 Drive Lock Rail, an M-LOK® compatible, free-floating AR-15 handguard. The tutorial covers the critical steps, including proper installation of the proprietary barrel nut to 40 ft.-lbs., securing the handguard with nut-bolt-sleeve sets torqued to 25-30 in.-lbs., and the use of a unique anti-rotation pin for enhanced stability, especially with SOLGW upper receivers. Essential tools required for the process are also highlighted.
