Hopup: I bought a TM hopup unit, firefly bucking, big out h-nub.
Barrel: Prommy 650mm 6.03mm TBB
Since I changed my cylinder out to a type 0 my guns getting 500fps with the stock M120, so my setup is reliable (not going to break at all) and quick trigger response.
P.S. If you're intending to change out your spring, KWA gb's and motors can handle m150 springs, but nothing much more because of the v2 gb being "naturally flaued".
Prob. gunna get flamed to shit for being a "KWA fanboy" but who cares, just my input.

500fps on M120:???: your joking right? There is no way you'll get 500 fps on m120 or you got a mislabeled spring.
