I bought the JACK at the Evike Airsoft Con, installed it and used it twice. 1 1/2 years later, I don't play anymore. I'm a bit of an amateur when it comes to Polarstars so I believe I installed it wrong. I think the alignment is off because my fps is randomly reduced. The gun also only shoots full auto, but sometimes it will shoot semi when selected. I'm sure someone who knows polarstars understand what is wrong, but i don't know what i'm doing so Im lost. At the bare minimum you can buy this for the JACK and have a ton of extras. Happy to answer any questions!
