Product Description
Fixed restriction valves for the VFC UMP GBB.
Understand that 3D printing is not an exact manufacturing method. Some light sanding might be required to make the part fit.
The main body outer diameter of the valve, where the gas passes through, must be between 7 and 6.9mm to fit in your nozzle.
What muzzle velocity values you get with these fixed restrictions is entirely dependant on temperature, bb weight, type of gas and your specific setup. The smallest valve with 3mm inner diameter should get you below 1J with 0.3gr bb. If you aim for around 1J, start with the 3.5mm valve.
The valve inner diameter increments are 0.25mm.
