USP Magazine lips

After a lot of testing and a couple of reworks my USP mag lips are finally finished and in a reliable working state. I've ran over 50 mags of 10 gels each through a set of mag lips with no problems and other testers have reported the same. Currently they come with a 3 month warranty* but that may be extended after further test on the test lips

*replacement lips will be sent out as standard untracked parcel
