Brownells Long Forcing Cone Chamber Reamer 20 Gauge

The Brownells Long Forcing Cone Chamber Reamer is a precision gunsmithing tool designed to extend and smooth the forcing cone in 20-gauge shotgun barrels. Lengthening the forcing cone reduces shot deformation, improves patterns, and can lower felt recoil. This reamer allows gunsmiths to perform professional-quality forcing cone work on 20-gauge chambers with consistent, repeatable results.
