I just wanna send it back, I brought a 'working' marker, I didn't buy a marker i'd have to take apart and fix every 5 shots.
Or just sell it on with a diff barrel.
Every gun Ive ever owned has had some degree of setting up, fiddling around and or sorting out before it works well. Thats just the way paintball is.
Now admittedly some guns just need me to put in a couple of different settings and they work perfect. These guns cost £700+
A few guns Ive had to basically learn the thing inside out to know whats up and how to make it run well. These guns are second hand purchases normally from people like yourself who cant be butt ar$ed to learn something about their new machine, think its broken and sell it on. Im afraid thats life bud. Welcome to paintball, have a nice stay!
