The TRU-CHOKEā¢-STYLE TOOLING MANSON PRECISION 12 GAUGE REAMER allows for the quick and easy installation of choke tubes, preferably using a lathe for superior results.
It includes precision ground tap and reamer from high-speed steel, with interchangeable pilot bushings for accurate bore alignment.
Designed for 12 Gauge shotguns, it can thread barrels too thin for Win-ChokeĀ®-style tubes, with an O.D. that is .020" smaller to fit thinner barrels.
