LBE Unlimited Rifle-Length Gas Tube Features The LBE Unlimited Rifle-Length Gas Tube is machined from 304 stainless steel seamless tubing a material chosen for its ability to withstand the repeated heat cycling and carbon fouling that a gas tube endures every time the rifle fires. The Melonite finish adds a layer of corrosion and wear resistance on top of the stainless base helping the tube shrug off moisture and carbon buildup that would otherwise accelerate pitting over years of use. Sized to rifle-length gas system specifications it directs gas from the port to the bolt carrier group at the correct timing for that platform length. Getting this length right matters since a mismatched gas tube can cause short-stroking excess bolt bounce or an over-gassed action. The tube ships with its roll pin included so a builder or armorer has everything needed to mount it to the gas block without hunting down a separate fastener. Black in color it keeps a clean factory-correct appearance under a handguard or free-float rail. LBE Unlimited designs and builds this component entirely in the United States part of a broader line that includes upper receivers bolt carrier groups barrels grips buffer tubes and springs. For anyone building repairing or upgrading a rifle-length AR-15 upper this gas tube is a straightforward American-made replacement part backed by a manufacturer focused on quality control.
