CMMG Gas Tube Kit Mid-Length with Roll Pin – AR-15

The CMMG Mid-Length Gas Tube Kit provides a direct replacement for worn or damaged gas tubes on AR-15 rifles with mid-length gas systems. This kit includes everything needed to restore proper gas system function: a stainless steel gas tube cut to mid-length specifications and a roll pin for secure installation to the gas block. Mid-length gas systems are commonly found on 14.5" to 16" barrels and offer a balance between carbine and rifle-length cycling characteristics.

Constructed from 304 stainless steel with a melonite finish for corrosion resistance and heat tolerance, this gas tube is built to withstand the high temperatures and pressures of repeated firing. Installation requires punching out the old roll pin and driving in the new one—basic armorer tools and experience recommended. Gas tube alignment is critical for reliable function, so take care during fitment.
