Power Tube Tip
Recently picked up a minimag and found air gushing down the barrel after firing a few shots.
Since the gun does not leak immediately upon airing up and only starts to leak after a few shots I am assuming the leak is coming from a bad sear?
I took the gun apart and replaced the power tube oring, the on/off teflon and urethane oring (on/off orings were shot). What I found however was a cut/gash on the inside of the power tube tip. Could this be causing air to gush down the barrel or would it be strictly internal such as the oring?
I am going to take my marker out this evening to check and see if the oring swap fixed the leak, and then further assume its the sear or power tube tip if leak is not fixed. What do you guys think?
