My mp7 uses a full magazine of gas on one or two shots. The o-rings on the mags are fine as they can hold gas for weeks easily so I'm assuming something in the gun is wasting all the gas at once some how. I have no idea and any suggestions would be appreciated
I use green gas and the gun is stock as i havent opened it up to tamper with any of the internals as im new to gbb and have no idea what i would be looking at.
