Ask politely, and ask for a couple of them. Thats the correct number. Have you checked you actually have the check valve in your gun? I use a piece of wire, to pick it out, and bend the end of the wire so it cant come off (for cleaning the gun). And pop it back in using the wire aswell. Easy lost though! @liam92 the check valve (aka. flow restrictor) is a small, plastic air port that slows down pressure flow in one direction. Its used to help control the movement of the bolt during firing, or in other words, they reckon its softer on paint all i know is, its certainly better with one!
Get a check valve in there, and test the gun. If there are other faults, come back on here and we'll sort it out. First things first, check valve. you could always ask KEE when you call them.
Perfect, Fat bobs will help. If not, Just Paintball, LiPS or any of the other retailers who stock Empire kit should be able to help.
Kee are random you gotta buy through someone else. I had this problem with my axe gotta explain to some one who doesn't service empire guns what parts your after.... Not sure really sure why but it did my head in personally. Rang kee yup we got what you need please either ring someone else or travel to your nearest dealer and hope he orders the right stuff. Its faster to just order from the states..
RAP4 have all the parts for the Mini, altho in all honesty i havent seen a check valve on the site, but then again i havent looked. edit 64p http://www.rap4uk.com/product-p/17531_bt.htm
