I have an issue that has to be the weirdest and hardest ive ever come across. Im working on a G&P m14, and no matter what i do, it shoots around 200fps, even on a m130 Modify spring.

Ive tested compression about a billion times, internally is fine, replaced the hop up rubber, replaced the nozzle, tried different springs, shimmed the Hop Up unit forward, shaved the tappet plate.

Im about to throw this out the window. I cant seem to find the issue. The air leak is Hopup-Gearbox but it shouldnt be there at all, but if i put bbs in the feed tube it shoots out.

I got it to shoot up to 375 on the m130 by accident once, but then it settled down to 200 again. If i hold the barrel in my hand and shove it into the gearbox i can get random readings of 460. So i know its hop up to air nozzle.

Im thinking its either wobbly nozzle syndrome, bad hop up misalignment or something else, but ive tried everything that has solved these problems in the past. Any suggestions or fixes guys?
