Sons of Liberty Gun Works 9.75" L89 M-LOK Handguard – AR-15

The Sons of Liberty Gun Works 9.75" L89 M-LOK handguard delivers a secure platform for accessories while maintaining a slim profile for improved weapon handling. The free-float design eliminates barrel contact, supporting consistent accuracy across strings of fire. M-LOK slots at the 3, 6, and 9 o'clock positions provide flexible mounting options for lights, grips, and other rail-mounted accessories.

Machined from 6061-T6 aluminum with a Type III hard-coat anodized finish in black, this handguard is built for durability under field use. The 9.75-inch length pairs well with carbine-length gas systems and mid-length barrels, offering coverage without excessive weight forward of the magazine well. Installation requires a barrel nut wrench and is compatible with mil-spec upper receivers. No proprietary barrel nut required—uses standard AR-15 threading.
