The Xvalve kit will have the proper orings for your lvl 10, the RT kit's come with a lvl 7 parts kit.
And while your at it, save yourself from having another aneurysm and order a .750 pin (use a regular oring with that pin not the quad) if you're not using that valve on a emag. That short of a pin on a mech mag will sometimes cause it to go full auto too.
