Brownells 11-18 45 Caliber Barrel Chamfering Plug Gauge

Description

Product Overview

The Brownells 11–18° .45 Caliber Barrel Chamfering Plug Gauge is a precision, hardened throat gauge used to quickly confirm you are working within the narrow diameter range that produces maximum accuracy. By slipping the plug gauge into the barrel throat, you get an immediate visual indication of whether the throat chamfer diameter is approaching optimum.

Key Features

• Designed to help you land the throat diameter within the narrow .004 in accuracy window
• Measures the 11° and 18° chamfer angle ranges for quick verification during setup and cutting
• Self-piloted, precision-ground, hardened stepped design for repeatable fit and reference
• Useful as a diagnostic tool when accuracy complaints point to throat/chamfer geometry issues
• Built for Brownells-designed chamfers and tools, where the reading aligns with that workflow

Take the guesswork out of throat chamfering on .45 caliber barrels and verify you’re approaching optimum diameter before you go too far.
