Considerations & Trade-offs

  • Fit is limited to optics with an outside diameter of 45.5–48.5 mm, so it may not suit every scope or accessory setup.
  • The flexible rubber sleeve is designed for a snug fit, which is useful for security but means sizing needs to be checked carefully before purchase.
  • The flip-up design is convenient for quick access, but it still adds a moving cover to the objective end that some users may prefer to keep as simple as possible.
  • This is an objective lens cap only, so it does not address protection for other parts of the optic.
