Maintenance is the mark of a master. Designer Joe Wu knows that there�s a world of difference between the recreational shooter and the one that�s spent years honing his skill. One notable difference: proper maintenance. Joe has given the AR Tool both a compact highly useful blade on a slip joint as well as a nine-in-one scraper tool. Built to quickly clean 12 critical surfaces of bolt components it�s equipped to restore an AR to working order at the range or in the field. The precision-cut tool is ideal for cleaning the bolt firing pin carrier and cam pin so your favorite range companion never slows down. - AR Cleaning Tools - Folding Knife Blade - 1/8 3/16 1/4 5/16 inches Hex Wrenches - Bottle Opener - Blade Length: 1.934 (49.12 mm) - Blade Edge: Plain - Blade Finish: Bead Blast - Blade Thickness: 0.089 (2.26 mm) - Closed Length: 3.087 (78.41 mm) - Handle: 2Cr13; Bead Blast Finish - Style: Multi-Tool
