Charlie36 Posted January 15, 2024 Posted January 15, 2024 Has anyone got a fix for a GM P Mag MWS that only takes about 2 seconds of gas before stopping itself filing anymore? It shoots about 5-10 BBs before running out of gas, even though I have held the gas canister against the filler valve for 20 seconds
Hunka1988 Posted January 17, 2024 Posted January 17, 2024 Have you tried venting as you fill? Briefly hold the knocker valve vent the gas and any air that has built up
