Using the 8-way outer barrel made specifically for the Tokyo Marui M4A1 MWS, Laylax created a custom 6-inch M4A1 MWS PDW. A good option to use for CQB games if you want to use the MWS, you get a compact GBB to go around tight places. Apart from the shortening of the front end, they also included a Krytac Trident Retractable Stock.
