I received, as a trade for a snowboard, the following: a smart parts shocker with a 68ci pure energy, dye boomstick, dye sticky grips and a smarts parts barrel. it also came with a electronic hopper. I have attached pictures. All I can tell you is that I pressurized the gun and it help air and fired when it was in the "eye-off" mode. So the eye and the electronic trigger frame do work.
Any questions let me know. if not make an offer. If you are more comfortable on ebay I can put it up there too.
