Selling my gss, used it a couple of times in games and is definately something different, doing 340fps when I last checked. Real wood quick detachable stock and a full metal reciever and suppressor. It has a cool feature which means that you have to pull the charging handle back when you put a new mag in otherwise it wont fire, and also has a cut off to stop dry firing though thos can be overridden using a small switch in the Magwell. They come with a mosfet installed and it sounds and shoots very nicely.
It has a Modify tbb, maple leaf hop rubber and nub, adapted to Deans and comes with 3 hi cap mags two are fine and one can be a little temperamental a sight rail and a nuprol 11.1v 1100mah lipo
