jay1988 Posted December 23, 2020 Share Posted December 23, 2020 hi guys so i run hpa and was looking at hpa tapping my pistol mags just wondering what sort of pressure you would need to run psi wise i was thinking about running it on same bottle and reg as my primary gun which is around 50-65 psi Link to comment Share on other sites More sharing options...
leadly Posted December 23, 2020 Share Posted December 23, 2020 I've just ventured into HPA and I'm sure I was running my AAP-01 and MK23 at 60 P.S.I which got an average of 300fps on 0.2's. It's all trial and error I guess. Link to comment Share on other sites More sharing options...
jay1988 Posted December 23, 2020 Author Share Posted December 23, 2020 i only ask because im hoping to t into the reg and run 2 lines off one bottle set at one pressure i didnt know if there was a specific opperating pressure Link to comment Share on other sites More sharing options...
Steveocee Posted December 24, 2020 Share Posted December 24, 2020 A good reference is green gas is about 110 psi at room temp. Duster is about 80 psi. I run my capa at 80 and get a really nice stable 0.99J with .25s if it's for a sidearm, I wouldn't bother as the additional line would be more hindrance but high FPS isn't a must for closer work anyway so you would be fine running at 60. You can always put a tighter barrel in the pistol and/or wider in the main to balance things out. Link to comment Share on other sites More sharing options...
