Whats the proper setting for the seal or o-ring tightness on the GBB mags? I heard a little hissing as I heald my ear next to the bottom of the mag. I tried to tight the clamp and the hissing got worse.
I backed it off and sprayed the mag down with silcone and let it set and turned gassing it, it did better but now the Gas leaks out after one mag, there was a time when I could reload the mag 2.5 to 3 times before the gas was gone.
What happened and what is the fix? Whats the name of the screw devise used to tighten or replace the o-rings seals?
Does anybody perform this task professional or hobby?
