The Reptilia Handguard, 15 inches, in Flat Dark Earth (brand part no. 100-340) is a free-float AR-15 handguard built around the Reptilia patented turn buckle attachment system for a rock-solid, tool-minimal mount to any mil-spec M4 upper receiver. Reptilia is known among military and law enforcement end users for rugged, mission-driven hardware, and this handguard brings that same reputation to the civilian AR-15 market. Machined from 7075-T6 aluminum billet and finished in a durable Type III Class 2 hard anodize, it shrugs off hard use in the field or on the range. Continuous M-LOK slots run the full length of the rail for flexible accessory placement, and the kit ships complete with the barrel nut and mounting hardware needed for installation.
