The WE M4 GBBR is an affordable, reliable, and customizable entry into the Gas Blowback M4 market. Featuring fully metal externals, as well as a steel bolt catch, the WE M4 kicks hard and snappy with every crisp pull of the trigger, while also being extremely gas efficient from its extremely lightweight magazines. 

This replica is designed after the 416 platform, but will take WE M4 parts.
