Sons of Liberty Gun Works L89 Rail 10.75" – AR-15 M-LOK Free Float Handguard

The Sons of Liberty Gun Works L89 Rail is a 10.75-inch free-float handguard designed for AR-15 pattern rifles. This M-LOK compatible rail replaces standard handguards to provide a rigid, lightweight mounting platform for accessories while improving heat dissipation and handling characteristics. The free-float design eliminates contact with the barrel, supporting better accuracy potential compared to drop-in handguards that contact the barrel assembly.

Constructed from 6061-T6 aluminum with a black anodized finish, the L89 Rail features M-LOK slots at the 3, 6, and 9 o'clock positions and a continuous top rail. Installation requires removal of the existing handguard and barrel nut; a barrel nut wrench and torque wrench are necessary. This is a drop-in installation for those familiar with AR-15 assembly, though professional installation is recommended if you lack the proper tools or experience with upper receiver work.
