Replace your original polymer AR-15 hand guard with a precision-machined quality aluminum drop in quad rail hand guard from Leapers UTG. This basic upgrade is easy enough for anyone to do while at the same time allowing you considerably more modularity over the stock hand guard. This drop in quad rail installs easily and quickly with no gunsmithing required and requires no permanent modification to the firearm. The quad rail sections conform to mil-spec picatinny rails allowing you to mount a whole host of accessories such as lights, lasers, foregrips and more. The drop in quad rail is made from high quality aluminum and features a durable hard coat anodized matte black finish.
