Magpul MAG551-GRY MOE SL Mid-Length Handguard AR-Platform Gray Polymer

Made in the USA, the MOE SL Hand Guard for AR15/M4 firearms with mid-length gas system and A2 front sight provides modular flexibility with M-LOK accessory slots in a lightweight, sleek, cost effective design. Reinforced, heat-resistant polymer construction provides operational durability without the weight and expense of an aluminum rail hand guard, integral riveted aluminum heat shield. M-LOK slots at the two, six and ten o'clock positions allow the attachment of optional Picatinny rail sections and other direct attach M-LOK accessories for the mounting of tactical lights, slings, grips, etc. A large front extension and lower lip protects the user from the hot front sight assembly and maximizes useable hand guard length. Easy to install utilizing existing delta ring and round front hand guard retaining cap with A2 front sight assembly*. Note- the Mid-Length MOE SL Hand Guard is a direct replacement for most factory plastic, two-piece, mid-length hand guards and requires a ROUND front hand guard retaining cap and rear spring-loaded delta ring (some mid-length firearms are equipped with a triangular retaining cap and are not compatible). Not compatible with piston operated AR platforms. Must be used with the A2 front sight assembly as other gas blocks are not compatible. If so equipped, the factory sling swivel must be removed from the A2 front sight assembly.
