JJ barrel wont work
I just dusted off my mini-mag (hyper-mag regulator) that has been sitting in my closet for about 10 years, and I did the level 10 tune up with all new internals and spring, as well as putting all new o-rings and seals on regulator. After working with it and getting no leaks I decided to shoot some paint and chrono. Imagine my surprise (and frustration) when I put on my JJ barrel and it wouldn't fire. If i pull the barrel out a bit, then it fires. I had no problems using a smart parts barrel or armson barrel. Any thoughts? Anyone have a similar experience?
P.S. I did try all of the springs and adding shims.
