So ive come across a strange mating issue with my gearbox and hop up.
If I push the hopup manually against the gearbox I get about 400fps, with a mag in about 250fps.
Now what ive noticed is when a mag is put in, the mag will literally move the hopup about 1-2mm away from the GB which I assume causes the airleak issue. Problem is it seems different mags move the hopup different amounts!
Now my question is what would be the best way to go about fixing this problem?
Here are some pics:
