The Lyman Tool Kit 68 Piece (Manufacturer Part Number: 7991361) is a comprehensive gunsmith screwdriver bit set engineered for firearm maintenance, optic mounting, and bench armorer assembly. Unlike standard hardware bits that taper and risk stripping delicate firearm fasteners, this kit features hollow-ground flathead bits that engage fastener slots with parallel contact to prevent cam-out and head marring. The set is housed in a hard storage case measuring approximately 23.2 cm (9.15 inches) in length, with a total weight of 2.115 lbs (approximately 0.96 kg), making it suitable for workshop benches and range-bag transport.

Key Features

  • Hollow-Ground Bit Design: Includes 32 specialized slotted bits designed to fit parallel gun screw slots precisely, eliminating slippage and marring during rifle, shotgun, and handgun maintenance.
  • Comprehensive Driver Assortment: Contains 17 hex bits (both metric and imperial), 6 Phillips bits (including 2 extended-length bits), and 4 six-lobe (Torx/star) bits for universal hardware compatibility.
  • Integrated Firearm Specialty Tools: Features dedicated armorers' bits, including 1 Weaver scope ring bit, 1 Glock front sight tool, 1 1911 grip bushing driver, and 3 roll pin punches (.062″, .093″, and .118″).
  • Manual Drive Versatility: Supplied with 1 driver handle, 1 bit extension, and 1 reversible compact ratchet wrench to provide additional leverage for stubborn screws and factory threadlockers.

Who is the Lyman Tool Kit 68 Piece for?

  • Firearm owners performing home maintenance and scope mounting — requires a 68-piece gunsmith screwdriver bit set with 32 hollow-ground slotted bits and dedicated scope-mounting profiles to install optics and adjust actions without slipping or stripping screw heads.
  • Benchtop gunsmiths servicing rifles, shotguns, and pistols — benefits from a portable 2.115 lbs workshop kit that integrates standard fasteners alongside dedicated roll pin punches (.062″, .093″, .118″), a Glock front sight tool, and a 1911 bushing driver for platform-specific field stripping and assembly.

Less suitable for: Applications requiring exact inch-pound torque thresholds for action screws or scope rings; users working to strict manufacturer torque limits require a dedicated calibrated torque wrench set.
