Sons of Liberty Gun Works L89 Rail 13.75" – AR-15

The Sons of Liberty Gun Works L89 Rail is a free-floating handguard designed for AR-15 platform rifles, offering a slim profile and full-length top rail for optics and accessories. This 13.75-inch model provides maximum rail space while clearing standard 14.5-inch barrels with pinned muzzle devices, making it ideal for shooters who want an uninterrupted sight picture and flexible mounting options. The L89's lightweight construction keeps the rifle balanced without sacrificing rigidity under hard use.

Machined from 6061-T6 aluminum with a hard-anodized black finish, the L89 Rail uses a barrel nut attachment system that interfaces cleanly with mil-spec upper receivers. M-LOK slots at the 3, 6, and 9 o'clock positions allow modular attachment of accessories without unnecessary bulk. Installation requires an armorer's wrench and torque wrench; professional installation is recommended if you're unfamiliar with free-float handguard installation.
