Description
The CMMG 55DA193 is a direct-replacement gas tube built specifically for AR-15 carbine length gas systems. Machined from stainless steel with a natural silver finish, this carbine-length tube drops into any standard AR-15 upper receiver that uses a carbine gas port position.
Offered as part of CMMG’s Build & Replace line, the 55DA193 ships with the correct installation roll pin so you have everything needed to swap a worn or damaged tube on the bench. It is intended for carbine length gas placement only and will not fit mid-length or rifle length barrel gas blocks.
