The Lyman Master Gunsmith Tool Kit (brand part no. 7991360) is a 45-piece screwdriver set built to cover the wide range of bit sizes and shapes gunsmiths and firearm owners run into during routine service work. Lyman assembled the kit so a single case covers slotted, Phillips, and specialty bits sized for sights, grips, scope mounts, and small screws across most firearm platforms, instead of hunting through mismatched drivers from a general hardware toolbox. It’s a practical, all-in-one addition for anyone doing regular maintenance, sight adjustments, or small repairs on their own firearms.

Key Specifications

• The kit includes 45 pieces, covering a wide range of screwdriver bit sizes and shapes.
