The barell is flawless with the right paint i ordered a jersey at the same time and have no recieved yet
I bought 2 of these barrel in the .681 and .685. Both shoot very well. Straighter than the stock 2 piece barrel. The finish and the portting is very well done. My only complaint would be the O ring. Both fell off after the first time I unscrewed them.
