Overview

This buttstock spacer is designed for hunters and shooters who want a simple way to fine-tune stock fit or add a clean finishing touch to a rifle or shotgun. Made from black polymer plastic, it offers a lightweight option with sanding and machining characteristics that make fitting and finishing more manageable. The slotted hole design helps it align with a wide range of hole locations, and the available thickness options allow it to be used alone or stacked to adjust length of pull. It is a practical accessory for stock customization, though it is intended for fitting and appearance rather than a performance upgrade.

Considerations & Trade-offs

  • This is a spacer component rather than a complete stock accessory, so it is intended for use with compatible rifle or shotgun stocks and existing hardware.
  • The slotted hole design offers installation flexibility, but fit still depends on matching the stock’s hole spacing and layout.
  • Thickness is fixed at 1/8 inch for this listing, so any larger length-of-pull changes would require using multiple spacers or a different thickness option.
  • The polymer material is described for easy sanding and machining, which is useful for fitting, but it also means final appearance depends on the user’s finishing work.
