Hi, I am relatively new to airsoft. I recently bought a KWA Kriss vector (
http://www.herooutdoors.com/kwa-kriss-vector-black/). I am going to customize with the goal of increasing my FPS. I plan on getting a mock silencer (

If so what size? Also, would you recommend I buy a hop up chamber? Any other thoughts on increasing performance of a the rifle is also appreciated.
