CNC Aluminum Hopup Chamber/Adjuster M4T set is precisely machined from a solid Aluminum block to perform accurately and consistently for Tokyo Marui MWS M4 Gas Blowback Airsoft Rifle.

The Hopup Adjuster M4T unit is built with a unique Rotary Dial Knob, a number indicator for precise hopup adjustment, and to prevent shifting under vibration. The Bolt Stopper/Damper is also adjustable to mitigate the Bolt Carrier bounce to eliminate double feeding of BBs.

The Hopup Chamber M4T unit is fully compatible with most GBB Rubber Buckings without losing FPS or dropping BBs ensuring the BBs shooting accurately and consistently on every single shot.

The Hopup Chamber M4T unit is also equipped with the Aluminum Locking C-Clip and Taper Locking Sleeve to keep the Inner Barrel securely in place without wobbling and twisting.

More than that, the Hopup Chamber/Adjuster M4T system is wisely designed and controlled by a Single-Arm-Control (PATENT PENDING) which allows the system to work precisely and accurately without unnecessary oscillations and instability on the Dual Arm Control systems
