Overview

These Delrin sleeves are designed to help mount a smaller-diameter scope tube in larger rings without marring the scope. The black matte finish keeps the setup subdued and visually consistent with the rest of the rifle. Because the reducers are sliced in half, they can be dropped on for straightforward installation with virtually any brand of rings in the listed size. Sold as front-and-rear-ring kits, they are a practical option for hunters and shooters working with mismatched ring and scope tube dimensions.

  • Sliced design supports easy drop-on installation

Considerations & Trade-offs

  • Designed for adapting larger rings to a smaller 26mm scope tube, so it is only appropriate when that size change is needed.
  • The reducers are sold as front-and-rear-ring kits, which means you need the full kit rather than a single-piece solution.
  • Installation is described as drop-on and sliced in half, but the fit still depends on the ring sizes listed and compatibility with virtually any brand of rings in those sizes.
  • The matte black Delrin finish is intended to stay visually unobtrusive, but the product is a functional adapter rather than a cosmetic upgrade.
