Both hopup and tighbores can increase FPS (those are what I always suggest upgrading before springs if you want more power) will. Once I got +50 FPS when I threw a longer tighbore in my hk416, so depending what brand you get you could get 20-25 extra FPS while remaining at the same length. And another proof for the rubber, Crunch threw a guarder clear in his 380 fps hk416 and ended up getting 410(IIRC, could've been 430)

The good news however, is you can now put a weaker spring in your M4, increaseing ROF and the lifespan of the mechbox.
