Just wanted to post an experience I had over the weekend. Was firing my marker in the backyard this weekend and I noticed that the marker would not fire consistently, and there was a lot of drop off. It would fire one ball fine, then the next would just flop out of the barrel, then it would not fire. After a minute it would fire 2 balls. I figured....maybe it was the battery, so I changed that, but the problem remained. I broke down the marker to lube it, but that didnt fix it either. I took the body off and notice that one of the hoses was pinched! When I changed the trigger and put the body back on I wasn't careful as to where the hoses where and one of the fittings was pressing down on it.
I repositioned the hose, screwed the body back down, good as new!
Remember people, just like on the ION, watch those hoses!
