  • Designed for 3/8" dovetail factory grooved receivers, so it is not a universal fit for all rifles.
  • Installation is tool-light, but it still depends on proper clamp engagement in the receiver grooves.
  • Silver finish may not match every rifle or optic setup aesthetically.
  • Intended for .22 Tip-Off Mount use, which limits it to that mounting style rather than broader accessory compatibility.
