Designed with versatility in mind, M-LOK slots at the two, six, and ten o'clock positions allow the attachment of optional Picatinny rail sections and other direct-attach accessories for the mounting of tactical lights, slings, grips, etc. Reinforced, heat-resistant polymer construction provides operational durability without the weight and expense of an aluminum rail hand guard. Large front extensions and lower lip provides additional operator protection from hot front sight assembly. The MOE SL Hand Guard - Carbine-Length is a direct replacement for M4 Carbine-type plastic, two-piece hand guards and utilizes the existing round front hand guard retaining cap and spring-loaded delta ring.Specifications and Features: Compatible With: AR-15 Country of Origin: United States of America Gas System Length: Carbine Material: Polymer Rail Style: Customizable
