Hi guys , just brought one new , filling the mag with gas i noticed theres no o-ring for the gas cann needle to seal against, so when filling up theres abit of gas loss and impossible to know when the mags full, im guessing there should be an o-ring?, also whats the best way to load these mags ? speed loader with gbbr adaptor? ,,cant belive how cheap the whole package feels especially the LAM unit, i was expecting it to not feel like a £20.00 spring pistol but the performance and sound suppression is pretty damn sweet! the suppressor on these really makes a differance....
