Hera Arms SFU Buffer Tube Folding Adapter Aluminum Black

The Hera Arms SFU Buffer Tube Folding Adapter was developed for the Hera Arms Triarii system, but it will work with any system using an AR-15 receiver extension tube that does not use an internal buffer and spring. It's great for bolt action folding skeleton stocks designed to accept AR-style receiver extensions and for pistol brace applications (other than AR-15s). This adapter WILL NOT work for standard AR-15s that require a buffer and spring to cycle within the extension tube.

Note: This adapter is not for standard AR-15s that require the use of a recoil buffer and recoil spring.
