Overview

These brass threaded inserts are designed to reinforce stock mounting points for sling studs, recoil pads, and triggerguards in wood, composite, and fiberglass stocks. The knurled exterior is made to hold epoxy bedding securely, while the internal 10-32 threads provide a solid interface for the included dome-top sling studs. Offered as a 2-pack with steel, matte blued studs, this setup is suited for hunters and shooters who want a more secure attachment point without relying on the stock material alone.

Considerations & Trade-offs

  • These inserts are intended for wood, composite, and fiberglass stocks, so they are not a universal solution for every stock material or application.
  • Installation depends on proper epoxy bedding and stock preparation; the product is designed to work with that added step rather than as a simple drop-in fix.
  • The package includes only two inserts and two dome-top sling studs, so larger projects or multiple rifles may require additional sets.
  • The internal threads are fixed at 10-32 tpi, which means compatibility is limited to hardware that matches that thread size.
