I love paintball guns. All of them. I don't usually care who makes them. I love them all.
(in no particular order)
Classic RT w/XMT ULERT body and custom ULT drilled valve and cocker threaded stock barrel. Still my go-to mech gun.
Smart Parts valve* BigEvil modded Hyperframe w/ULT, custom trigger switch and trigger* Silver Eclipse parts* BOA barrel. Keeps up with the best of them as long as I don't try to shoot it over 16 bps.
Eclipse Vert feed minimag
Splash green Eclipse set* I-frame* ULT* Xvalve* Vert feed powdercoated minimag body. Won 3rd place at one of the Tunaball's Most Awesome Mag contests.
Smart Parts AA barrel* Air America Whispering Death expansion chamber* SP wood grips* A reproduction of my very first Automag. The only thing that was different was that I had a metal grip frame on it and not a carbon fiber one.
