Hey guys I'm new to HPA, I've just installed a kythera into my SAI GRY and I'm looking at regulators now. Thinking of going with the polarstar MRS anyone got one or would you recommend something else?

I read about this problem on my ICS CXP-UK1. Something to do with the motor spinning too far on semi auto mode when running a UK spec lesser fps spring and partially rechambering a BB (with the spring release function completing the rechambering). Then when you fire it loads a second BB. That's why they downgrade the motor and spring on the officially imported UK1s and disable the spring release.
