fx 2000 diy reg

Recommended Posts

hia all, i hope i can pick some brains, i have fitted a diy reg to my webley fx 2000 and was pleased with results as shot string is very consistent with less than 10 fps spread but around every 6 or 7 shots it drops around 70 fps for just the one shot then goes back to being consistent again. the reg i have set to around 130 bar , the gun is a 177 using aa field power around 11.20 ft lbs . any ideas why i keep getting this odd power loss around every 6-7 shots, any help appreciated ,

I'm assuming youve copied a design a dont understand how it works? I wont tell you, work it out you will understand then, its cycling for one of two reasons.

 

Could be a few things but 130bar is rather excessive. On that simpe layout and ease should be looking around 25% reduction in pressure for starters with above mod/s.
