100% Made in the USA — Not Repackaged, Not Re-Labeled This is a genuine Squirrel Daddy muzzle wear gage made by our U.S. operation. We do not buy imported gauges, repackage them, and claim USA origin. Our tools are made, checked, packed, and shipped from our operation with real support behind them. Avoid Mystery-Sourced Copies Copies may look similar in a photo, but precision, markings, material, finish, and consistency matter when you are measuring barrel wear. This is the original USA-made Squirrel Daddy design, sold direct by the maker. How to Read the Gage The handle is marked .30. The laser marks show the last two digits of the measurement. For example, a reading of 15 equals approximately .3015". Insert the gage gently at the muzzle and read the mark at the contact point. Wear Interpretation Note Many shooters consider readings near .303" to indicate a well-worn muzzle. Actual acceptable wear depends on the rifle, barrel, ammunition, and accuracy expectations.
