"Bought it to fix a boneyard ER25k and it was well worth it. I only wish it was slightly more powerful, but 400fps was still enough for me to play an effective DMR Role. I recommend buying a slightly stronger spring and upgrading the gearbox
by Gaven F. on 01/03/2019
"This gearbox was apsolutely useless, it says it is compatible with sr25, However the cylinder and gears are normal size found in your average m4! Only thing they elongated was the cylinder head which makes it even more unique and HARDER TO UPGRADE! If you are buying this because you want to upgrade your sr25 or gr25 with custom parts DO NOT BUY. That said, this gearbox does work with all compatible models if you just want to drop it in.
