Air Venturi Alpha Transfer Port Kit

Air Venturi Alpha This kit allows you to adjust the transfer port size. The kit contains 6 transfer ports of different orifice diameter: white: 1.8mm green: 2.2mm yellow: 2.7mm brown: 3mm pink: 3.4mm black: 4mm The transfer port should be installed with the flat face facing downward. Due to the fact that the muzzle velocity depends on factors such as barrel length, regulator setting and hammer force, we cannot provide velocity number for each transfer port. Buyer is responsible to make sure that the muzzle energy is within local allowed limits.
