Description
The CMMG 55DA15F is a pistol-length gas tube kit purpose-built for AR-15 pistol and PDW platforms. This direct-replacement gas tube restores reliable cycling performance on short-barreled AR builds running a pistol-length gas system.
Constructed from stainless steel with a natural silver finish, the 55DA15F is engineered to handle the heat and gas pressure of sustained semi-automatic fire. It drops into the standard AR-15 gas block location and ships complete with the installation roll pin needed to lock it securely in place.
Whether you are replacing a worn-out tube on an existing AR pistol or assembling a new PDW-style build, this CMMG gas tube kit delivers the fit, finish, and durability expected from one of the industry’s leading AR component manufacturers.
