Product Features
- Stainless Steal Construction Made from 100% corrosion-resistant stainless steel with laser-etched markings for consistent measurement.
- Compatibility Designed for use with M1 Garand, M1 Carbine, M1A, M1903, M1903A3, and M1917 rifles chambered in .30-06, .308 (7.62 NATO), .30 Carbine, and M2 Ball.
- Easy to Use and Read Gauge readings range from 0.0 to 3.0+, with 0.0 indicating a .300" bore (new). 0.5 = like new (.3005"), 1.0 = excellent (.301"), and 1.5 = good (.3015"). A 2.0 reading (.302") is fair, while 2.5 (.3025") is poor. 3.0 or higher suggests the barrel should be replaced. Proper re-crowning can often restore barrels reading up to 2.5.
- Accurate, Non-Distoring Readings Laser process does not affect the gauge diameter, allowing reliable readings without underestimating wear.
- Made in the USA by NDZ Performance Proudly designed, manufactured, and laser-engraved in our U.S. facility supporting American jobs and delivering tools trusted by gunsmiths and collectors alike.
