11mm to 20mm Weaver Adapter Mount

Model: 11mm to 20mm Weaver/Picatinny Adapter Mount
Material: Aluminum alloy + steel clamping screws
Compatibility: 11mm dovetail groove / Commonly found in air rifles, small-caliber rifles, and some vintage air guns
Weight: Approx. 30–50g
Size: Base is compatible with 11mm rails, top converts to standard 20mm Picatinny/Weaver specifications
System: This 11mm to 20mm herringbone adapter is a bridging accessory designed to solve rail specification incompatibility. The body is made of high-quality aluminum alloy through precision machining, with a black anodized surface treatment, combining lightweight and scratch-resistant properties. Its main function is to directly convert the traditional 11mm wide “dovetail groove” rail commonly found on firearms into the now mainstream 20mm (Picatinny/Weaver) herringbone interface. It can be securely locked onto the base via built-in steel hexagonal or hand-adjustable clamping screws, maintaining excellent zeroing stability even under vibration. This allows players to easily add modern red dot sights, sniper scopes, holographic sights, or various optical accessories to previously restrictive platforms.
