Maxx Model CNC Alu M4 Hopup Chamber SV (VFC SCAR -L/H).
CNC Aluminum Hopup Chamber SV unit is specially designed to improve accuracy, durability and ensure consistent air seal for VFC SCAR-L/H AEG series. The Hopup Chamber SV unit has a precision rotary dial design for fine hopup adjustments, also re-engineered the hopup levers and concave nubs to work best with R-hop and Standard-Hop to keep the BBs shooting straight and accurate on every single shot. The Hopup Chamber SV unit is designed to accept the nozzle length from 21.00mm to 21.25mm on VFC SCAR-L and 38.50mm to 38.75mm on VFC SCAR-H, and also fully compatible with most aftermarket soft and hard rubber bucking without losing FPS or dropping BBs. The Hopup Chamber SV Housing is equipped with a new CNC Delrin Locking C-Clip design to hold barrel tight without wobbling and twisting. With the new extended sliding arms design on both side of the chamber housing, the hopup unit is always centered, straight and air tight at all times when closing the receivers.
