The Brownells Magna-Tip See-Thru ring bits are precision-engineered tools designed for the installation and removal of scope rings with see-through mounts. These extended-length bits allow users to access the mounting screws through the scope rings, facilitating efficient engagement without the need to remove the scope.

• The extended length of these bits allows them to reach through transparent scope rings, providing direct access to the mounting screws
• This design feature obviates the necessity to detach the scope during installation or calibration, thereby maintaining the scope's alignment and zero integrity
• Optimized precision - each bit is engineered with a hollow-ground design to ensure an exact fit in slotted screws, significantly reducing cam-out risk and potential damage to screw heads or firearm components
• Constructed from hardened steel, these bits provide outstanding strength and durability, rendering them ideal for repeated use in rigorous gunsmithing applications
• Compatible with Brownells Magna-Tip handles
