Sons of Liberty Gun Works L89 Rail 11.75" – AR-15 Free-Float Handguard

The Sons of Liberty Gun Works L89 Rail is a free-float handguard designed for AR-15 platform rifles where reliability and clean mounting surface matter. This 11.75-inch rail provides nearly full-length coverage on carbine-length gas systems while leaving room for most muzzle devices. The design eliminates the need for anti-rotation tabs, using a continuous barrel nut interface that promotes consistent lockup and simplifies installation. M-LOK slots at the 3, 6, and 9 o'clock positions allow modular attachment of lights, grips, and other accessories without adding permanent weight.

Machined from 6061-T6 aluminum with a Type III hard-coat anodized finish in black, the L89 Rail is built to handle heat and impact without excessive bulk. Installation requires a barrel nut wrench and proper torque—this is a straightforward job for anyone comfortable with AR assembly, though a gunsmith can ensure correct timing and fitment if preferred. The package includes the rail, barrel nut, and necessary hardware.
