Was doing an inspection of my gear box and noticed my piston doesn't seal with the the cylinder. Or at least not by hand. The Gun shoots fine at 300 fps with a m90 spring. No complaints about the gun I just don't understand? isn't the idea that the piston makes a seal in the cylinder?
Hears a video I made showing the lack of seal... also in the video the o-ring isn't so visible, but its there!
