Nice barrel: poor fitment

As others have stated this barrel is manufactured with such tight tolerances that it will likely not fit without modification from a gunsmith. It's listed as a drop in barrel. Brownells tried to make it right by sending a second barrel which I experienced the same issue with. After growing weary that a third barrel would fix the issue I was only refunded a partial amount from Brownells with nothing to show for it. Pretty disappointing in both highly regarded company's. Shop accordingly.

No-Go for M&P 2.0…………

Does not work for M&P 2.0…… didn’t even hook up inside the slide. Starting the return process now…..
