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.
