I did change the o ring on the Pison head and there was pressure when i tested it by putting my finger on the sylinder head and did notice that there pressure.

It just bugs me that I put a better nozzle on the M249 then the stock one and the FPS dropped by 120, but in this operation i also took apart my hopup the clean the barrel.

could the hop up take away from the fps aswell?

and the parts are all in mint condition, most of them brand new.

but i will invest in some cylinder gease to see if it helps.
