Precision Machined Aluminum CNC Hopup Chamber for M4W

Precision Engineered HPA Hopup Chamber for Unmatched MTW Performance
Elevate your airsoft rifle’s accuracy with our CNC-machined aluminum hopup chamber, designed exclusively for HPA MTW Milspec, Forged, Billet, and MTW-9 series platforms. Experience flawless consistency shot after shot – no more flyaways or FPS drops.

Why This Upgrade Dominates:
– Micro-Adjustment Rotary Dial: Fine-tune your hopup effortlessly with the aircraft-grade aluminum dial. Perfectly pairs with R-Hop or Standard-Hop setups using precision 4mm bucking nubs (6mm optional).
– Zero-Compatibility Issues: Works seamlessly with MTW M4-length nozzles and virtually all aftermarket buckings – soft or hard rubber. Maintains optimal air seal and velocity without sacrificing BB retention.
– Eliminate Barrel Wobble: Features an interchangeable 11mm inlet adapter (11.5mm/12mm optional) that centers perfectly in your engine nozzle. Combined with CNC brass side wings sliding smoothly into barrel slots, vibration is history.
– Locked-In Precision: Our proprietary Delrin C-clip secures your inner barrel rigidly, preventing twist and shift during rapid fire.

Engineered for Perfectionists:
Forget plastic housings that flex under pressure. This unit’s solid aluminum construction ensures thermal stability and impact resistance. Whether you’re running heavy BBs in competitive matches or demanding field conditions, expect unwavering trajectory control and effortless grouping tightness.
