The Lantac USA M-Spec Gas Tube (brand part no. 01MSPECGTRIF1) is a rifle-length +1 gas tube built from 306 stainless steel extruded tube as part of Lantac’s M-Spec gas system lineup. The rifle-length +1 configuration extends the gas system slightly beyond a standard rifle-length tube, a setup some AR-15 builders use to fine-tune cycling on a specific barrel and gas port combination. Lantac manufactures the tube from 306 stainless steel for consistent performance and durability under sustained firing. It is a direct AR-15 accessory for anyone building or tuning a rifle-length gas system.
