Boyt Harness Co BASE Swivel Bit Set for Precision Firearm Upgrades

Upgrading a rifle stock for dependable sling attachment requires precision and the right tooling. Whether you’re a professional gunsmith or a do-it-yourselfer working in a home shop, clean, repeatable holes and controlled countersinking are essential to avoid chipping laminates or damaging synthetic stocks. The right bit set makes the job fast and accurate while preserving the value and finish of the firearm.

Key features and why they matter

• One-step drilling: Reduces bit changes and improves alignment, which keeps holes concentric for a secure swivel fit.
• Countersink fixture: Prevents overcutting and surface splintering on wood laminate and synthetic stocks.
• Depth indicator: Ensures consistent screw depth so sling swivels sit flush and don’t loosen under load.

For sellers and buyers, this Boyt Harness Co. product brings a practical balance of precision and affordability. Use the included drill sizes to match your swivel hardware; the 1/2″ and 3/4″ woodscrew bits are suitable for standard sling plates, while the 3/4″ machine screw bit covers metal-to-metal mounting scenarios.

Installation tips from a tactical perspective

Clamp the stock and protect the finish with masking tape. Start slow and let the countersink fixture do the work—its depth indicator prevents walking and keeps resin or laminate from chipping. For dense synthetic stocks, use steady pressure and back the bit out periodically to clear chips. A pilot or guide block can help maintain perfect perpendicularity on curved or slender fore-ends.
