Hey Steve, by no means am I saying it's your fault! We found the same issues with freak barrels when making e-mag extreme bodies. I was just giving some feed back.
I honestly love the gun. Although I am intending to get it stripped, polished and re-annodised
(do you think that will cause any problems with tolerances etc?)
Whats the chance of getting a pump handle like the one you put on the special gold guns? They looked so good and I'd love something similar on my pump
