So I haven't played in about 10 years and a buddy and I decided we wanted to play a little this summer. Since my mag has been sitting for a decade, it likely needs a valve rebuild (Retro Valve). I ordered a rebuild kit but since I haven't had this thing apart in 10 years I'm afraid I'll screw something up. Does anybody have an explode view of a retro valve I can use for reference? Also, am I correct in understanding an X valve is this same in both function and design, just the X valve is made of aluminum and comes with standard level 10 and is 100% ULT compatible? Thanks in advance guys.
