Look at the o-ring at the back of the nozzle; it's not an expanding o-ring: if it's not pressing right up against the inside of the BBU you're losing gas.
And you didn't answer: does the mag get colder with the RATech nozzle than with the stock nozzle?

The rubber O-ring seal in the back is just tight around the nozzle and its not loose also there is a little bit of friction inside the bolt carrier from the O-ring ,
i went and i got a new set of O-ring and i tried just a little bit ago and it gives the same results as well it shoots 3 or 4 sometime 5 shots before it lose force and starts spiting BBs .
And ya the magazine gets colder than when i use the plastic nozzle which is weird .
