CMMG Receiver Extension kit Pistol

The CMMG Receiver Extension Kit Pistol is a dedicated component assembly designed for completing a pistol lower receiver build. This kit is ideal for builders and gunsmiths looking to assemble custom pistol platform receivers or replace worn recoil system components in existing lower groups.

The kit includes a CMMG pistol receiver extension, a carbine buffer assembly, and a carbine action spring, providing the essential recoil management system for a functioning pistol platform. The receiver extension tube is designed to accept standard carbine buffer assemblies, ensuring reliable cycling and consistent recoil impulse.

This kit is particularly beneficial for those standardizing their build parts on CMMG components, as it reduces the number of separate transactions needed to acquire all three components. By integrating seamlessly with your choice of lower parts kit, it helps create a complete pistol lower group assembly.
