Brownells
The Brownells Armorer's Gen II Standard Kit is a complete gunsmithing toolkit purpose-built for AR-15 and M16 rifle maintenance, repair, and customization. Whether you're a dedicated armorer, a serious rifle builder, or a hands-on enthusiast who takes pride in keeping your platform rifle running flawlessly, this kit consolidates the specialized tools you actually need into one organized, portable package. Everything ships in a rugged Pelican hard case with custom foam inserts and a slide-out aluminum rail system—built to mil-spec standards and designed to survive the field or the bench.
The Standard Kit equips you with precision tools across every category of AR-15 and M16 service work. Torque wrenches ensure fasteners are set to specification; receiver vises and action blocks hold the rifle steady during disassembly; specialized wrenches and sight tools handle everything from barrel nuts to front sight posts. Roll pin holders and punches in five sizes, pivot pin detent tools, and headspace/alignment gauges take the guesswork out of critical jobs. You also get a carbon scraper, chamber mirror, handguard tool, and the snap ring pliers and magnetic screwdriver handle that round out practical everyday work.
The kit is modular by design: the foam layout leaves room for future upgrades if you eventually add Premium Kit components for M4-specific tools. That means your investment grows with your needs rather than forcing you to replace the whole setup. With high-quality, purpose-designed tools in one place, you cut frustration, reduce the chance of damage from makeshift solutions, and finish jobs faster and more confidently.
