CMMG
Overview
The Cmmg AR-15 Gas Block Assembly is a low profile component designed for a .750-inch gas block diameter, making it a reliable choice for standard gas systems. Constructed from steel and finished with a nitride treatment, this gas block effectively channels gas from the barrel to cycle your action while maintaining a streamlined profile that fits under handguards without adding bulk. This assembly is often found in builds utilizing a carbine gas system, particularly for those chambered in 5.56 NATO.
