Cmc Ar15 Gas Tube Intermediate Lngth

The CMC AR15 Gas Tube Intermediate Length is a precision-engineered gas tube designed to optimize cycling reliability in intermediate-length direct impingement AR-15 rifles. Manufactured by CMC Triggers, this component is machined from 304 stainless steel and finished with a durable nitride coating that significantly enhances corrosion resistance and wear characteristics. For operators and shooters who demand consistent performance across variable ammunition loads and environmental conditions, this gas tube delivers the gas metering precision necessary for reliable semi-automatic function.

The nitride finish applied to the 304 stainless steel substrate provides three critical advantages: enhanced fatigue strength to withstand repeated pressure cycles, improved wear resistance against internal carrier contact, and superior corrosion resistance in both dry and humid operational environments. Intermediate-length gas tubes regulate impulse between carbine and rifle configurations, making them the optimal choice for mid-length handguards and moderate-velocity ammunition. The precision machining ensures consistent internal and external dimensions, which directly translates to uniform gas flow rates and predictable bolt carrier velocity—factors that determine whether your rifle cycles reliably or experiences short-stroking failures.

This gas tube suits builders and maintainers who are replacing OEM tubes, upgrading worn components, or tuning gas system reliability in intermediate-length AR-15 platforms. Law enforcement armorer shops, military contractors, and civilian shooters running duty rifles benefit from the extended service life and corrosion resistance of CMC's stainless nitride design. Whether you're running a patrol carbine, training platform, or duty rifle in saltwater or harsh climates, a quality gas tube is a foundational component that prevents catastrophic carrier tilt and ensures your rifle feeds, fires, and ejects ammunition without hesitation.
