Good evening
I currently have a rapid 7mk2 in fac with direct flow and fill to 170 bar to get approx 3 mags of consistency down to around 120 bar.
This pushes the 18.13 jsb around 985 FPS average
I have the option of a short core reg ( kev Gi think ) and was hoping this is compatible with my set up so I could fill to 250 bar in the carbon bottle to get more shots around the 40 ft/lbs mark
What are people's thoughts on this please
Thanks
With a fast flow, it's the valve & barrel port size that control the air flow & smooth out the sweet spot.
With a reg the shooting pressure is set lower with the barrel port opened to allow the same volume of air per shot as the smaller port at higher pressure.
So it's rather more involved than just fitting a reg.
