Birchwood Casey BSDS Basic Screwdriver Kit 22-Piece Slotted/Phillips/Torx/Hex

The Birchwood Casey Basic Screwdriver Kit (BSDS) is a 22-piece gunsmithing and firearm maintenance bit set built around the four screw head types most commonly found on modern rifles, shotguns, and handguns. Everything stores neatly in a compact plastic case for bench or range-bag use, giving the user a focused, no-nonsense selection for field-stripping, scope and mount work, action adjustments, and general repairs.

The bit selection covers Slotted heads in 3, 4, 5, 6, and 7mm, Phillips heads in PH1, PH2, and PH3, Torx heads in T10, T20, T25, and T30, and Hex heads in 2, 3, 4, 5, and 6mm. Combined, the 22 pieces address the vast majority of flat-head, cross-head, star-pattern, and Allen-style fasteners the shooter or gunsmith will encounter. Slotted and Phillips cover classic screw work, Torx covers the star-drive fasteners common on optics rails and accessory mounts, and Hex rounds out the set for the socket-cap screws found throughout firearms and accessories.

Housed in a plastic storage case that keeps every bit organized and portable, the BSDS is an affordable bench staple or range-bag backup for anyone who maintains their own firearms.
