  • The flexible rubber sleeve is designed for a snug fit, which may feel tight during installation on some scopes.
  • This is an objective lens cap only, so it does not provide protection for other parts of the optic.
  • The snap-flat spring is designed to stay out of the line of sight, but the flip-up design still adds a moving component that should be checked for secure closure.
