Tapco 16810 AR Extension Tube Kit Commercial

Don't rely on inferior buffer tubes when assembling the collapsible stock for your AR-15 style rifle. The INTRAFUSE buffer tube from TAPCO is manufactured using impact extruded 7075 T6 aircraft aluminum with a Mil-Std 171 matte black exterior coating and a Mil-Spec dry film lubricant inside the tube that makes the action extremely quiet. Proudly made in the U.S.A.
