Product Options


The MOE SL Hand Guard for AR15/M4 firearms with carbine-length gas system and A2 font sight* provides modular flexibility with M-LOK accessory slots in a lightweight, sleek, cost effective design.

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 M-LOK 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. A large front extension and lower lip protects the user from the hot front sight assembly and maximizes useable hand guard length.

Made in U.S.A.
