    Have you got the standard O ring in it? if so i would ditch that. its complete sh1te. also make sure the cylinder head is not leaking and if it is wrap it in some PTFE tape and reassemble. also check what type of cylinder is in it. it should ideally have a port in it rather than being perfectly smooth. reason being the ROF on those is so fast you can get a vacuum from the backward motion of the piston after the shot and this will interfere with the velocity of the BB. :)

    Make sure the air nozzle is attached to the tappet plate, if you're new enough to gearboxes, its an easy over sight.

    Bar that, what Masada said.

    the o ring is the stardard one that came with it it is guarder Polycarbonate Ventilation Piston Head with Bearing the cyclinder is the standard one that came with the gun it is not ported so that means i need to get one and the tappet plate is conected to the nozzle.

    Id say the o ring is the most likely culprit. ive replaced 4 of them on these rifles.
