It quickly and accurately measures bore diameters from .300" to .303" using laser-etched permanent markings. Compact and portable, it fits in your pocket and works with any .30 caliber barrel, making it an essential tool for gunsmiths, collectors, and savvy buyers to assess barrel wear and maintain firearm performance. ## Description Muzzle wear gage for any .30 caliber rifle barrel. Measures from .300 to .303 diameter very simply and quickly. 100% made in USA from alloy steel with direct reading permanently laser etched markings. Typically, when it gets up to .303" diameter its pretty well worn out, less than that depends on how picky you are. Gage reads .30 on the handle and segments indicate last two digits, for example .30 + 15 = .3015 diameter. Review: Great Tool - I cannot attest to the extreme accuracy of this tool but I think it is. Regardless it works extremely well for comparison purposes of different .30 cal barrels. In gauging a new rifle it shows no wear, used but accurate rifle it shows very little wear and on some used unknown accuracy rifles for sale, it shows different amounts of wear. Some of which deserve no further evaluation. I take it with me whenever I look at used rifles. Review: Great value for the price - I had been thinking of buying a muzzle gauge for some time, but was put off by the price on some devices. When I saw this one, I thought what could I lose. When I got mine, using a quality micrometer, I checked this device, and I was pleasantly surprised. Now a valued addition to my bench tools. As the prices of collectable pieces are going up, having both a throat erosion and muzzle gauge in hand, checking pieces during deliberations makes more sense than ever. ## Features - .30 Caliber Muzzle Wear Gage is 100% Made in USA - Quickly measure .300" to .303" diameter bores - Direct reading markings are permanetly laser etched onto stainless steel body - Small enough to carry in your pocket - Works with any .30 caliber barrel ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00N9H5F7Y | | Best Sellers Rank | #667,928 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #4,367 in Gunsmithing Tools | | Brand Name | Squirrel Daddy | | Customer Reviews | 4.7 4.7 out of 5 stars (123) | | Date First Available | September 2, 2014 | | Item Package Dimensions L x W x H | 4 x 2 x 0.4 inches | | Manufacturer | Fisher Gauge | | Package Weight | 0.06 Pounds | | Part Number | az20-183 | | Size | One Size | ## Images ![.30 Caliber Muzzle Wear Gage Bore Gauge 100% USA - Image 1](https://m.media-amazon.com/images/I/410ScsAUcUL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Tool *by O***O on March 31, 2019* I cannot attest to the extreme accuracy of this tool but I think it is.

But this is a great tool to quickly check a rifle with a .30 bore for excessive muzzle wear. Small enough to stick in a pocket and not notice ## Frequently Bought Together - Squirrel Daddy .30 Caliber Muzzle Wear Gage Bore Gauge 100% USA - NDZ Performance Muzzle Bore Wear Erosion Gauge Tool for M1 Garand M1 Carbine M1A M1903 M1903A3 M1917 Enfield 30 Caliber in Stainless Steel - Forster Products 30-06, Headspace Gauge, SAAMI Dimensioned, Rimless, Hardened Steel, Precision Ground --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/30581999-30-caliber-muzzle-wear-gage-bore-gauge-100-usa](https://www.desertcart.hr/products/30581999-30-caliber-muzzle-wear-gage-bore-gauge-100-usa) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-25*
