Round tube free-float handguard for the AR-15 platform. The hollowed-out wall design keeps the tube stiff around the barrel while cutting weight, and the smooth exterior gives a clean look for classic clone builds or a comfortable grip surface for casual shooters who do not want KeyMod or M-Lok slots.
Torque the barrel nut per manufacturer spec (usually 30–80 ft-lb range for AR-15 platforms) and time it to clear the gas tube. Once torqued and timed, thread the handguard tube on and secure. Verify the gas tube is not pinched against the tube ID before test-firing.
