Hi all, i need some help. Just put together my SRS gen 3 covert today and installed the silverback M150 spring, im getting just 380 fps on .2's. I thought this would be a lot higher as its only now about 50 fps up on the spring that comes with the gun.
I have added hop but still i get around 380.
Any ideas? Thanks in advance.
