I've had my MR-1 for about 2 weeks. I've shot about 1500 balls thru it using a 72 cu in 3000 psi tank. The problem I'm having (besides going thru 2 ball detents) is taht the marker acts as if the tank is empty. The gauge reads 2000 and it works on my custom 98 w/out a problem. Any ideas??
Also when you chopped/shear off the ball detent, anyone else have the marker jam up and not fire??
