Modify MWS Full CNC Lightweight Bolt Carrier with Nozzle

Full CNC Steel Lightweight Bolt Carrier (with Aluminium Rear Section) Engineered for Tokyo Marui M4 MWS / URG-I GBB rifles. Machined from high-strength steel with weight-optimised cuts and an aluminium rear balance section, it reduces reciprocating mass while enhancing cycling speed and recoil response. Compared to the stock cast-alloy carrier, this upgraded design offers: • Exceptional impact resistance, no cracking or deformation• More precise weight distribution for smoother and faster cycling • Aluminum rear section for optimal inertia & sharper recoil impulse • Wide platform compatibility with TM MWS / URG-I and most aftermarket parts • Stable under full-auto, high-pressure gas, and cold-weather use A must-have upgrade for players who demand maximum performance, durability, and a refined recoil feel.
