Our Enhanced M-LOK (EM) Handguards provide a lightweight free float design for your custom AR15 build. The M-LOK system allows advanced modularity past the current 1913 picatinny rail system. Machined to mil-spec dimensions and engineered to perfection this handguard eliminates bulk while retaining strength and stability. 1.78″ inside diameter fits most muzzle devices and 1.5″ suppressors. Compatible with low profile gas blocks. Gen 2 Features: Quick disconnect sling socket at the 3 6 and 9 o’clock positions. New profile for the continuous picatinny top rail. Additional milling along flats to aid with gripping and add visual appeal. *Please note – This handguard is specific to the AR15/M4E1 platform. It is not compatible with the M5 .308/M5E1 platform.
