A friend gave me his old marker because he hasn't played in 8 years and thought I might get some use out of it. The problem is I know nothing about PMI markers and I cant seem to get it to work properly. When I cock it I can get it to shoot once then I need to cock it again. I tried putting in heavier madman spyder springs but still couldn't get it working right.
I think the valve is a rat valve and when I tested it I was using compressed air and a cp regulator on it. I had the reg pressure at 425. Any help in getting it working would be great. also if you could identify it for me that would be nice.
