I purchased these from Sinden directly. AUCTION is mainly for first gun which has never
  been used and is brand new tested from factory. I used the second gun for a couple days and it worked but seemed gradually weaker. it still powers up.  both have REALISTIC recoil vibration.
THE second USED GUN SHOULD BE CONSIDERED FOR PARTS ONLY..   THE NEW GUN is still brand new.
one brand new gun withe recoil has retail price of $225

The one that is used I am listing with this item just because I have two items. The used item is considered parts only non-functional even though it Powers up. The optics seemed gradually weaker over just a couple days use. So whatever the reason it's still considered non-functional to me whether or not it's an easy fix. 

This auction is mainly for the brand new functional gun that was tested at the factory before I received it. It is brand new and fully functional. The second gun which is used is considered non-functional and for spare parts. 
I'm sure if you're attacking you can get it going because the system recognizes it and it Powers up it just has weak optics that need to be held closer to the screen could be calibration I don't really know. 
So one brand new light gun fully functional.  One parts only light gun, partially functional.
