Castellan 11mm Dovetail to 20mm Picatinny Rail Adapter — Aircraft Aluminum

Bridge the gap between legacy dovetail platforms and modern Picatinny accessories with the Castellan 11mm-to-20mm Rail Adapter. Machined from high-grade aluminum alloy, this adapter gives you instant access to the full Picatinny/Weaver accessory ecosystem — red dots, scopes, flashlights, and more — without replacing your existing rail system.

• Universal Dovetail Compatibility — Fits standard 11mm dovetail rails found on air rifles, rimfire rifles, and classic hunting platforms.
• Full Picatinny Output — 10-slot, 20mm Picatinny top rail accepts virtually any modern optic or accessory with a Weaver/Picatinny mount.
• Aircraft-Grade Aluminum Alloy — Lightweight at ~60g, yet rigid enough to maintain zero under repeated recoil cycles. Matte finish reduces glare in the field.
• Precise Dimensions — Length: 125mm | Height: 17mm | Top rail width: 20mm | Bottom groove width: 11mm.
• Tool-Compatible Installation — Secure clamping mechanism locks onto the dovetail groove for a stable, wobble-free fit.

Ideal for hunters and sport shooters looking to modernize their optics setup without changing their platform.
