I have a rifle using a 300mm inner barrel using an overvolumed cylinder, and an amazing R-Hop job shooting 0.30g BBs at 1.4j. It shoots further and straighter than most guns out there, including most PTWs and HPA platforms. Straight as an arrow.
All you need is the right combination of air volume, barrel length, hop up modding and tuning, and ammo weight to get amazing results.
