tightened the base screw, not the top one. having not tinkered with the top valve of mags, its just tightned by turning the screw in the nipple that gets depressed?
Yeah. There is a special tool but can be done with a wide bladed flat screwdriver. They can work loose or it may be the 'o' ring letting gas by. Regards
thanks, will give it a gentle turn once its empty, letting them sit a night to see if the gas holds until tomorrow
