To be a quality manufacturer in the modern era, you should have no more defectives than 3.5 in a million units. It is obvious that T/C doesn't abide by this philosophy from the many posts on this forum of people sending back barrels, having difficulty mounting scopes etc. I guess my point for the fellow is this: if you want guranteed performance right out of the box, and Encore is not the best option, there are many better options for the money. If he wants to be able to switch barrels, the risk of a problem may be acceptible.
