Like thomasinaz said OKFC05, "if he can ever get one". They're sold out practically everywhere so thousands of people are buying them and replacing the OEM barrel. Why would this be? I think your hit and miss with accuracy on these guns with the tolerances they have. IMO They're built like an AK to run no matter what, but if you want target grade accuracy you're going have to do something with some of them. Maybe not all, but some if you read alot of the different forums. Otherwise thousands of people couldn't be wrong and htere wouldn't be a market for them. Don't get me wrong, the accuracy is "ok" and I love the M&P lineup, but necessity is the mother of invention.
