Designed as a direct-fit component for standard AR-15 and AR-10 upper receivers, this tube channels high-pressure gas from the barrel gas port to the bolt carrier via the carrier key, keeping the direct-impingement system cycling reliably.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eAt a full \u003cstrong\u003e15.16\"\u003c\/strong\u003e overall length, this is the proper \u003cstrong\u003erifle-length\u003c\/strong\u003e gas tube configuration, intended for use with rifle-length handguards and corresponding gas-block placement on extended front ends. The \u003cstrong\u003eblack nitride\u003c\/strong\u003e finish is not a surface coating but a surface-hardening treatment that penetrates the steel, increasing wear resistance and providing long-lasting protection against heat, corrosion, and carbon fouling in the harsh environment inside the upper receiver.\u003c\/span\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eWhether you are building a new complete upper, replacing a worn factory tube, or upgrading to a more corrosion-resistant component, the CMC Triggers gas tube delivers a precision fit and consistent function. \u003cstrong\u003eCMC Triggers\u003c\/strong\u003e is well-known in the AR-15\/AR-10 community for quality drop-in triggers and tight-tolerance machined components, and this gas tube reflects the same commitment to quality manufacturing.
