hey hope it works out for you...i hope i am not jacking this but it is related. I am having an issue with Betsy's hop up ...It seems to be on all the time. I turn it all the way down and I am getting about 100 to 120 feet before the bb starts to fly to the moon on .3s
I have my hop up on table and it seem sit has a fair bit of bb damage now...it has white streak on the inner hop up rubber where the bbs have been impacting the rubber in the hopup chamber upon loading. I am wondering could the nub be too large? I am also wondering if Betsy needs a better rubber installed ... I am wondering if I installed the rubber for under less powerful or cqb rifles so many moons ago when I put the hop up back in... :banghead: ... what hop up rubber do you recommend for a 400fps AEG? I like to shoot .28s or .3s... (ty Groo72).
Could a hop up rubber for a cqb AEG (330 to 350) be the cause?
Just wondering if I should replace the whole hop up or not. (I do have a spare

)
any hoo any helpful input is always appreciated.
