Whether you're a serious collector, a range tinkerer, or a professional gunsmith, the Birchwood Casey 40-Piece Professional Gunsmithing Screwdriver Set covers the fasteners you'll encounter across rifles, pistols, and shotguns. This kit combines a full range of driver types—slotted, Phillips, Pozidriv, Torx, and hex—in one organized system, eliminating the hunt for the right bit when you're deep in a detail strip or mounting an optic. Built on seven decades of reputation for quality (Birchwood Casey has been arming serious shooters since 1948), this set is designed for the precision work that matters.

The 40 pieces span multiple sizes within each driver family: slotted bits from 3mm to 9mm, Phillips from PH0 to PH3, Pozidriv PZ0 through PZ3, Torx T10 to T30, and hex drivers in both metric (1.5mm to 6mm) and fractional (1/16" to 9/64") increments. Two extra-length bits—a 50mm Phillips PH2 and 50mm slotted 3mm—reach fasteners in tight or recessed locations. Everything stores in a clear-front plastic container, so you can spot what you need without emptying the whole set onto your workbench.

This is a gunsmith's toolkit for hunters, competition shooters, and armors who do their own maintenance. It handles scope base installation, trigger adjustment screws, safety mechanisms, and furniture work on everything from classic 1911s to modern AR platforms. The organized case makes it shop-ready or travel-friendly for remote maintenance.

Frequently Asked Questions

What fasteners will this gunsmithing set handle?

The 40-piece kit covers the vast majority of screws found on modern and classic firearms: slotted adjustment screws on triggers and receivers, Phillips fasteners on scope bases and rail systems, Torx security screws on controls, hex socket fasteners on furniture and attachments, and Pozidriv variants. The range of sizes ensures a snug fit without stripping.

Will these bits fit my scope mount or AR rail base?

The set includes Phillips, Torx, and hex drivers that cover common scope-mounting hardware and AR-style rail fasteners. However, the exact fit depends on your specific optic or accessory—check your mount's documentation for the required drive type and size, then confirm it's in the kit.

Is this suitable for professional gunsmithing or just home maintenance?

This is a professional-grade set used by gunsmiths and serious armorers, though it's equally practical for hunters and shooters doing regular field maintenance, trigger adjustments, or accessory installation. The organized case and comprehensive selection make it equally at home in a shop or a range bag.

What's included in the case?

The set ships with all 40 driver bits and two extra-length bits (50mm) organized in a clear-front plastic storage container for easy access and portability.
