Yes, when used together with the A&K Masada Nozzle (sold separately), this kit allows the Fusion Engine to interface with the a&k sr25's original M4 type hop-up chamber. The hop-up chamber is a component that affects the trajectory and range of BBs, so maintaining compatibility with the original hop-up design can help maximize performance.
