Abstract: A firearm handguard having two identical halves, or half guards, can engage the barrel nut of certain firearms to thereby provide a mounting rail system. The barrel nut attaches the barrel to the receiver. The half guards can be separately positioned in engagement with the barrel nut before fastening them together. The fastening operation can cause the half guards to clamp onto the barrel nut. Alternatively, the front handguard cup of some firearms can prevent the handguard from slipping forward while the rear barrel nut engagement prevents handguard rotation. Free floating variants, however, must clamp onto the barrel nut.
