well, i'm not flaming anyone, but my personal opinion is that everyone needds to be a little self sufficient. paintguns are mechanical things and mechanical things often need adjustments- a loose feedneck needs some duct tape, a loose twistlock barrel needs some tape under the orings, a detent needs an extra oring. Who cares? is it the ned of the world? no. if I have somethign that doesn't work, I go to the box of parts and come up with a way to make it work. I don't just throw up my hands and cry.
think back to working on guns in like '90 and I needed a lot of homemade fixes. it's all good.
