CMMG AR15 Buffer Retainer Parts Kit – AR-15 Lower Receiver

The CMMG AR15 Buffer Retainer Parts Kit provides the essential components to secure your buffer assembly in the lower receiver during assembly or replacement. This small but critical kit includes the buffer retainer and spring that prevent the buffer from falling out of the receiver extension when the upper is removed. It's a necessary part for any AR-15 build or repair where these components are worn, lost, or damaged.

Manufactured to mil-spec dimensions for reliable fit and function. The buffer retainer is machined steel with a Parkerized finish for corrosion resistance. Installation is straightforward but requires care—the spring tension can make the retainer difficult to hold in place during assembly. A punch or slave pin can help align the retainer while installing the receiver extension.
