Cmmg Receiver Ext Kit Carbine Ar15

The CMMG Receiver Extension Kit Carbine AR15 is a mil-spec receiver extension assembly designed for AR-15 carbine builds and lower receiver projects. This kit includes a carbine receiver extension, end plate, carbine buffer, and recoil spring, providing essential components for reliable cycling in a 5.56mm NATO AR platform.

The receiver extension serves as a crucial interface between the lower receiver and the buffer tube assembly, managing bolt carrier group dwell, buffer strike velocity, and recoil control. Constructed from anodized aluminum, it offers durability and corrosion resistance, making it suitable for extended training and field use.

This kit is ideal for builders and operators looking to maintain or upgrade their carbine platforms. Whether assembling a first AR-15 from a stripped lower or refreshing an aging buffer system, this receiver extension kit simplifies the process by providing all necessary components in one package.
