"I got this installed in my JG MP5 RAS, adds FPS, but im not sure how much. Now it goes through the top of a can though. Helps accuracy alot, from about 20-25ft (approx) the groupings were the size of a finger! I'd definitaly buy a Mad Bull tightbore for any other guns I have and I'd recommend it to my friends that are going to be buying tightbores soon.
