MOE Handguard, Black, Carbine Length The Magpul MOE Hand Guard for AR15/M16 rifles with carbine-length gas systems combines the light weight of a standard hand guard with modular flexibility. Slots at the two, six, and ten o'clock positions allow for optional mounting of Picatinny rail sections for tactical lights and other accessories. Reinforced, heat-resistant polymer construction provides operational durability without the weight and expense of an aluminum rail hand guard. Front extensions and lower lip provides additional operator protection from hot front sight assembly.
