The Arrow Arms HK 416A5 conversion kit for the TM M4 MWS GBB platform is an extremely well crafted, Japanese made product to turn your M4 into the HK416A5. The first thing you will notice with this kit is the uniformed color, the receivers match with the rail which matches with the buffer tube.
As made to work with the MWS, the kit can in turn take full advantage of the efficient system seen from the TM GBBR. Adding to realism, you even get a mock gas block and piston set which is fully spring loaded.
