Got a scope or red dot sight with an 11mm dovetail mount, but your rifle only has a 20mm Picatinny or Weaver rail? No problem! This little adapter solves that. It's a simple, low-profile riser that clamps onto your 20mm rail on the bottom and provides an 11mm dovetail groove on top. The model is 94. It's unbranded but brand new in the package. Perfect for mounting airgun scopes, older optics, or certain European sights onto modern sporting rifles or air rifles with standard rails. Makes your gear compatible without having to buy a whole new mount. Super easy to install – just tighten the screws. A must-have adapter for any shooter or hobbyist who mixes and matches optics and firearms.
