asg sp-01 shadow gbb

[NathanH2015]

having an issue with my c02 mags, they don't hold gas as it escapes quickly out of the main valve, may not be related but the gun isnt always cycling with all its kick sometimes its barely enough to cycle the gun and fire the bb. its brand new any one else had this issue and managed to sort it?
cheers guys

vids of both issues, they are on my goggle drive nothing dodgy lol
