Product Description

 

CNC Aluminum Hopup Chamber MXW unit is precisely machined to perform accurately and consistently on HPA MTW Milspec, Forged, Billet and MTW-9 series.
The Hopup Chamber MXW unit is built with an aluminum Rotary Dial Knob for fine hopup adjustments, the precision Hopup Lever and 4mm Bucking Nubs (6mm Bucking Nubs are optional) to perform best with R-Hop and Standard-Hop to keep the BB shooting accurately and consistently on every single shot.
The Hopup Chamber MXW unit is designed to accept the HPA MTW Engine M4 nozzle length, and fully compatible with most aftermarket soft and hard rubber buckings without losing FPS or dropping BB during use.
The Hopup Chamber MXW unit is wisely equipped with a self-centering inlet O-ring to ensure the hopup unit is inserted exactly in the center of the 11mm to 11.5mm inner bore HPA Engine nozzle outlet without wobbling.
Also mounted the removable CNC Brass Side Wings to slide smoothly into the outer barrel slots, and included an advanced CNC Delrin Locking C-Clip to hold the inner barrel tight in place without wobbling and twisting.

***Test results: FPS might be increased from 10FPS to 30FPS over the stock setup. Please check your FPS!

Comfortable and stylish
Size: 12, Color: Black
I'm very pleased with these shoes. I rarely write reviews, but these are extremely comfortable and stylish. I bought a black pair and a brown paid. Many times I have to get a wide, but the standard size 12 fits me well. Easy to slip into, yet still snug while walking. I feel like the price is reasonable too. Good cushioning, not too thin of a sole.
