FPS problem

Hey guys,
I'm gaving problems with my cylinder. When I shoot with a m170 spring, almost no air shoots out of the cylinder head. There are no leaks because i checked every place where therr ecould be one and no air came out when I shot. I recently lubed the piston o ring and basically the whole cylinder with white lithium grease, but that didn't really do anything. I checked the spring and it works perfectly on another sniper. I am running an action army zero trigger with its piston, the stock cylinder and spring guide and m170 spring. Do u have any idea on how i could fix this fps issue?

You sure no air is coming out? Take the cylinder unit out of the rifle and use an allen key or something to pull back the piston and release it with your finger on the cylinder nozzle. It it moves whilst your finger is covering the hole then there is a leak!
