They are notoriously bad for leaking. Same with Desert Eagle mags. Those guns were designed to run on duster. If it doesn't leak, great, use it and enjoy. If it does leak, you can try to swell up the bottom seal with Dow #55 o-ring lube. That works. Or some guys have tried to seal up that joint with silicone, that may work.

Democracy is two wolves and a sheep discussing what's for dinner.
Freedom is the wolves limping away while the sheep reloads.
Never confuse freedom with democracy.
