The WE M4 series are all built to a 1:1 ratio to their real steel counterparts. Featuring realistic field stripping and a functional forward assist button the WE M4 CQBR is a force to be reckoned with. Built fully in metal with ABS furniture, the WE M4 weighs only slightly heavier than the fully loaded Real Steel M4 at 3.3kg. Aesthetically the WE feels nice and solid with no play between the upper and lower receiver at all, this version features no markings for those requiring the more anonymous visage. The blowback feels nice and firm yet with lower recoil, so if you prefer a low recoil GBB, then this is the gun for you!
