CMMG Forward Assist Kit - Complete Assembly with Spring & Installation Pin (Black)

Building an AR-15 from a stripped upper receiver means sourcing every component—including the small parts that seem to vanish when you need them. The CMMG Forward Assist Kit solves that problem by bundling the forward assist assembly, spring, and installation pin into one complete package. If your upper came bare and you need to get that charging handle assist working, this kit has everything you need to finish the job without hunting down individual pieces from multiple suppliers.

The forward assist is a practical addition to any AR-15 build, giving you the ability to seat a round or ensure bolt closure with a firm tap to the rear of the upper receiver—useful on the range, in the field, or anywhere you want absolute confidence in chambering. Since many stripped uppers arrive without this assembly pre-installed, having a ready-to-install kit with the spring and pin included saves you time and the frustration of piecing together hard-to-find small parts.

CMMG designs this kit for straightforward installation on compatible AR-15 upper receivers. The black finish matches standard AR components, and the complete assembly approach means you won't be left searching for a missing spring or wondering if you have the right pin. Whether you're completing a first build or finishing a parts-kit upper, this forward assist kit gets you one step closer to a functioning rifle.
