Sons of Liberty Gun Works L89 Rail 7.75" – AR-15

The Sons of Liberty Gun Works L89 Rail is a 7.75-inch free-float handguard designed for AR-15 platforms, offering a slim profile with full-length M-LOK attachment points. This rail provides a rigid mounting platform for lights, lasers, and foregrips while keeping the overall weight down for handling speed. The 7.75" length is optimized for carbine builds and provides clearance for most suppressor configurations.

Constructed from 6061-T6 aluminum with a hard-anodized black finish, the L89 Rail uses a proprietary barrel nut system that requires an armorer's wrench for installation. The low-profile design maintains a clean sight picture with standard height iron sights. Installation requires basic gunsmithing tools and knowledge of AR-15 assembly procedures.
