Castellan 11mm/20mm Dovetail to Picatinny Rail Mount Adapter — Aluminum Alloy

A compact, dual-standard rail adapter that bridges 11mm dovetail and 20mm Picatinny platforms in a single mount. The Castellan Dovetail-to-Picatinny Adapter lets you attach flashlights, lasers, and scopes to tube-style mounts with full adjustability — all in a 41g, full-metal package built to absorb recoil and hold zero.

• Dual Rail Compatibility — Fits both 11mm dovetail and 20mm Picatinny/Weaver rails. One adapter covers both standard platforms without additional hardware.
• Full Metal Construction — Aluminum alloy body with extra shock resistance. Built to withstand sustained recoil without loosening or shifting.
• Flashlight, Laser & Scope Ready — Designed to mount flashlights, laser sights, and scopes onto tube-style mounts. Fully adjustable for precise positioning.
• Compact & Lightweight — Dimensions: 120 × 20 × 5mm. Weight: 41g. Minimal footprint adds capability without adding bulk to your setup.
• Secure Clamping — Positive clamping mechanism locks onto the rail for a stable, wobble-free fit across both dovetail and Picatinny standards.

Compatible with 11mm dovetail and 20mm Picatinny/Weaver rails. Suitable for air rifles, rimfire platforms, and hunting setups.
