Product Overview

The Maxx CNC Aluminum Hopup Chamber SV is specially designed to improve accuracy, durability and ensure consistent air seal for the VFC SCAR-L/H AEG series.

The precision rotary dial design for fine hopup adjustments and re-engineered hopup levers and concave nubs are designed to work best with R-hop and Standard-Hop to keep the BBs shooting straight and accurate on every single shot.

Designed to accept nozzle lengths from 21.00mm to 21.25mm on VFC SCAR-L and 38.50mm to 38.75mm on VFC SCAR-H, it is also fully compatible with most aftermarket soft and hard buckings without losing FPS or dropping BBs.

The Hopup Chamber SV Housing is equipped with a new CNC Delrin Locking C-Clip designed to hold the barrel tight without wobbling and twisting. With the new extended sliding arms on both side of the chamber housing, the unit is kept centred, straight and air tight.
