HPA Brass Inner Barrel
In house lathed HPA Brass Inner Barrel, designed for HPA.
These barrels have a 7.65mm inner diamter. The method behind this is to create an even air pocket between the gel and barrel, giving it a more accurate escape from barrel.
These are made of a high quality brass material.
Adjustments will need to be made to your FCU to properly tune this barrel in. We recommend running a minium of 100 PSI with these barrels, as more air will be used each shot, but we are finding better grouping and accuracy with these barrels.
Made in a range of sizes: 100mm, 200mm, 300mm, 400mm, 500mm, 600mm, 650mm
