Aero's Enhanced M-LOK Handguard provides a lightweight free-float design for your custom AR15/M4 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 hand-guard eliminates bulk while retaining strength and stability. It features built-in anti-rotation tabs, scalloped rails, quick disconnect sling socket at the 3, 6 and 9 o'clock positions and additional milling.
