Abstract
Disclosed herein is a hand guard attachment system comprising: a barrel nut configured to be attached to a firearm; the barrel nut having an outer surface; and a cam lever rotatable from a first position allowing the hand guard to be longitudinally positioned about the barrel nut to a second position clamping the hand guard onto the barrel nut. The hand guard attachment system may be arranged wherein the hand guard is rotationally adjustable without indexing relative to the barrel nut. The hand guard attachment system may comprise a longitudinal locking system cooperating with the clamping system and prohibiting longitudinal movement of the hand guard relative to the barrel nut when engaged.
