I’ve never had problems running any brand of mag in my G&G AFV , and I’ve run god knows how many different ones through it over the years ?
plus another one saying completely avoid ANYTHING that has moving parts(to be honest I’d even think twice about stuff that DOSEN’T have moving parts !) sold by ‘’Nuprol’ .
I genuinely think they must travel the world specifically looking for the cheapest , nastiest, poorest quality kit they can find to stick their brand name on !
