SOLGW L89 13.75″ M-LOK Handguard — Black

The L89 handguard from Sons of Liberty Gun Works is a 13.75-inch M-LOK rail designed for AR rifles. Its patent-pending Drivelock system, developed in collaboration with Icon Defense, uses three independent wedges that engage a proprietary barrel nut to clamp the rail with precision. The handguard features a slightly larger internal diameter to provide additional clearance around the gas block and improve rigidity compared with prior designs. Constructed from aircraft-grade aluminum with an anodized finish, the L89 is built for durability and accessory compatibility.
