CMMG FA kit great upgrade
Reviewed on April 22, 2026Verified with Build

CMMG forward assist kit is a great upgrade over the basic assembly that comes with a stripped upper. Spring tension is correct, pawl movement is smooth. Roll pin alignment was straightforward. Drops in with the right punch.

CMMG FA kit complete
Reviewed on March 13, 2026Verified with Build

CMMG forward assist kit comes complete with the pawl, spring, and roll pin. Saves sourcing parts individually. Spring tension is correct, doesnt stick or float. Roll pin alignment was on the first try. Solid budget upgrade.

CMMG forward assist kit has slightly different black anodize than my CMMG receiver in direct light. Mechanically perfect, spring tension is correct, pawl moves smoothly. Drop in install with the included roll pin.
