It's finally going to be released! Tokyo Marui now announced with finality that the much awaited Tokyo Marui M4A1 MWS Gas Blowback Rifle will be released on the 13th of November 2015. Originally set for release in 2014, the engineers went back to the drawing board as they were not satisfied with its durability. They updated the design this year with the ZET System that emphasizes on the endurance and provides a different approach at gas blowback technologies for rifles.

"In order to prevent the bolt catch of wear and damage due to bolt open, the mechanism is attenuated by receiving the impact of the bolt to move forward instead of bolt catch... it is 'Z-System'. With the Z-System, M4A1 MWS has achieved unprecedented durability."
