CMC AR15/AR10 Gas Tube - Nitride Coated Mid Length

The CMC AR15/AR10 Gas Tube – Nitride Coated Mid Length is a precision-engineered gas system component designed for AR-platform rifles requiring reliable, consistent cycling under demanding operational conditions. Built by CMC Triggers, a brand trusted by law enforcement and military professionals, this gas tube serves as the critical conduit between your barrel and bolt carrier group, regulating propellant gas flow to drive the action.

The mid-length configuration balances dwell time and gas pressure distribution, making it ideal for 5.56 NATO and 7.62×51 NATO platforms seeking smoother recoil impulse and reduced carrier tilt compared to carbine-length tubes. The nitride coating provides exceptional corrosion resistance, hardness, and durability—essential when operating in harsh environmental conditions, salt air, or high-round-count training cycles. This finish protects against rust and erosion without adding significant weight.

Tactical professionals, military armorers, and competitive shooters benefit most from mid-length gas systems when shooting suppressed or unsuppressed configurations. The precision machining ensures a consistent bore diameter and wall thickness, critical for proper gas regulation and component longevity. This gas tube is compatible with both AR15 and AR10 platforms, making it a versatile choice for various builds.
