Type-A TDC Hop-Up Set for Tokyo Marui MWS

The Type-A Hop-Up Set is a complete precision upgrade designed specifically for Tokyo Marui MWS gas blowback rifles and compatible MWS-spec platforms. CNC machined from a solid block of 6061-T6 aluminum, the Type-A features a true TDC (Top Dead Center) adjustment system for precise, repeatable hop-up tuning. Supplied as a complete kit with both aluminum and rubber pressure nubs, a 70° ARCHWICK TRIDENT silicone bucking, and all required installation components, it delivers improved consistency, accuracy, and long-term durability. 

Precision CNC Construction

The hop-up chamber is CNC machined from lightweight yet durable 6061-T6 aluminum, providing exceptional dimensional accuracy and rigidity compared to cast or molded alternatives. The robust construction ensures long-term durability while maintaining precise alignment between the hop-up chamber and inner barrel. 

True TDC Adjustment System

The Type-A utilizes a Top Dead Center (TDC) adjustment system that applies pressure directly above the bucking for finer, more consistent hop adjustment. A hardened steel adjustment screw and steel retaining plate provide a more secure and stable adjustment mechanism than conventional C-clip designs, while an integrated O-ring minimizes adjustment drift caused by recoil and vibration. :contentReference[oaicite:2]{index=2}
