The CMMG Gas Tube Kit Mid with Pin is a precision stainless steel gas tube assembly designed for AR-15 mid-length gas system builds and repair work. This component delivers reliable gas port regulation essential for proper cyclic function in modern piston-driven or direct impingement platforms. CMMG's mid-length gas tube configuration supports balanced recoil impulse and extends component life across a wider range of ammunition power levels compared to carbine-length systems.
Constructed from stainless steel, this gas tube resists corrosion from both moisture and carbon buildup, critical for shooters operating in humid environments or conducting extended range sessions without immediate cleaning. The kit includes the installation roll pin, eliminating the need for separate sourcing during assembly. Mid-length gas systems typically deliver softer recoil impulse and reduced bolt carrier group speed compared to carbine-length alternatives, translating to faster sight recovery and lower component wear during sustained fire. The tube's dimensional compatibility with standard AR-15 upper receivers ensures straightforward integration into existing builds.
This kit serves AR-15 builders, gunsmiths, and rifle owners performing maintenance or component replacement. Whether restoring a legacy rifle, upgrading a platform, or completing a new build from parts, the CMMG mid-length gas tube provides a verified solution backed by a manufacturer with established reputation in the tactical rifle community. The inclusion of the installation pin streamlines the assembly process and ensures users have every component needed for proper installation without additional hardware purchases.
Mid-length gas systems represent an established balance point in AR-15 platform engineering, offering a compromise between the faster cycling of carbine-length tubes and the softer recoil of rifle-length systems. CMMG's stainless construction and precision tolerances ensure this tube will function reliably across standard and +P ammunition across thousands of rounds of use.
