Samson Bufferless Receiver Extension, Black Aluminum

The Samson Bufferless Receiver Extension (Samson part no. 040616201) is a black aluminum receiver extension built for AR-platform rifles running an alternate recoil system that does not require a traditional buffer and buffer spring. Samson machines the extension to mil-spec dimensions so it threads into a standard AR-15 lower receiver without any special fitting. Because it is designed to work without a conventional buffer, it is intended for builds using a recoil-mitigating system, such as certain gas- or spring-piston setups, rather than a standard direct-impingement buffer tube configuration. It is a purpose-built part for builders running one of these alternate systems who need a compatible receiver extension.
