ABSTRACT:
A handguard used on a firearm with a barrel nut having tines spaced about the outer periphery. The handguard includes a tubular body in which the inner surface adjacent the proximal end has a diameter larger than an outer diameter of the barrel nut and smaller than a diameter defined by the outer tips of the tines. Grooves are defined in the inner surface and extend longitudinally from the proximal end toward the distal end. The grooves are spaced apart around the periphery so as to correspond with the tines on the barrel nut. The body further has a circumferentially extending channel in the inner surface, spaced from the proximal end so as to receive the tines therein with the barrel nut in the tightened position to allow limited rotation of the body around the barrel relative to the barrel nut until the tines are aligned behind lands between the grooves.
