The TRU-CHOKEā¢-STYLE TOOLING MANSON PRECISION 20 GAUGE REAMER is designed for easy choke tube installation using a lathe for superior results, though hand installation is possible.
It features precision ground high-speed steel construction with interchangeable pilot bushings and an enhanced end relief for a faster cut.
Specifically for 20 gauge shotguns, the tool has a .675"-44 tpi specification and is suitable for barrels too thin for Win-ChokeĀ®-style tubes.
