Hi, Have a problem with my TM MWS mag, can not fill them up enough with Propane, mag is Verson 2. think it is filling valve, it is as if there can be no more in and then it weighs 460 g, and some of them for I only up to 458 g
Does anyone have experience with that product (G&P CNC Adjustable Power Nozzle Valve for Marui MWS)
