The LBE Unlimited Rifle-Length Gas Tube (brand part no. ARGTR) is a direct-fit gas tube sized for AR-15 rifle-length gas systems and machined from 304 stainless steel. It ships complete with its own gas tube roll pin, so there is no need to source a separate small part to finish the install. The 304 stainless construction stands up to the extreme heat cycling inside the gas system far better than a plain steel tube, resisting the pitting and carbon buildup that shorten a lower-grade tube’s service life.
