Magpul MOE Hand Guard, Carbine-Length for AR15/M16, Black. The Magpul MOE Hand Guard combines the light weight of a standard hand guard with modular flexibility. Designed with versatility in mind, slots at the two, six, and ten o’clock positions allow the attachment of optional Picatinny rail sections and other accessories for mounting tactical lights, slings, grips, etc. Reinforced, heat-resistant polymer construction provides operational durability without the weight and expense of an aluminum quad rail handguard. Front extensions and lower lip provides additional operator protection from hot front sight assembly. Compatible with both "direct impingement" and most piston-driven gas systems. Easy to install utilizing existing delta ring and round or triangular front hand guard retaining cap.
