Arcturus Centaur B Buffer Tube Adapter

Although the Centaur B has an excellent ACR style stock, I wanted to try something different given the amount of M4 stocks on the market. With some edits to this model, one could also easily route the annoying battery location to a buffer tube since the Centaur B has holes drilled in the rear of the receiver. This adapter must be used with a slide on airsoft M4 buffer tube and not a threaded one. Additional hardware required is an M5 Screw, washer, and nut.
