I take it that the 350 fps is with .20's I gather that info by him saying its easily upgradable (meaning its not upgraded right now) and I know that gun doesn't do 350 with .30's stock. Hope that helps until he can reply

yes this gun is stock. its easy to work on snipers because its not complicated. also i had to glue the stock back together. i used plumbers glue, witch melts plastic together and its as hard as a rock (good as new). 350 with .20's. ($50 for everything) i can paint it for an extra $10.
