So what type of cylinder is this? a 4?


I know installing it in my mp5 will get it better accuracy since its got a full cylinder, but will it get me any fps improvements? or will that only come from upgrading the spring?

Minimum to no fps gain. Unless you're using a barrel that is too long for such a largely ported cylinder

It shouldn't affect accuracy at all. If that MP5 has a very short barrel it could give a slight FPS boost because the piston will start compressing the air at a more optimal point. It will make it less loud almost definitely.

hmm, alright thanks. Cant hurt to have the correct cylinder for the barrel length.
