Precision Engineering for Superior Accuracy

Machined from solid 6061 T6 aircraft-grade aluminum, this chamber checker is crafted using the same Clymer reamers employed in professional barrel chambering.

• Measures minimum case diameter to confirm proper headspacing and chamber fit
• Verifies maximum overall length to prevent feeding or extraction issues
• One-piece, non-adjustable construction eliminates calibration errors for dependable results every time
