Top Quality

Got this threaded barrel for my M&P 9mm. Dropped in and works fine with a suppressor attached! Bore of this barrel is perfect, no chatter or other imperfections.

Great barrel

Dropped in easily as a replacement for M&P 9 2.0 - 4.25" unthreaded barrel. Accuracy/grouping atleast on par with OEM barrel, might be slightly better at 10m
