11mm Dovetail to 20mm Picatinny 10 Slots Rail Brackets
Description
11mm Dovetail to 20mm Picatinny Adapter — Bridge the Rail Gap
Many air rifles and rimfire rifles ship with 11mm dovetail rails — incompatible with the vast Picatinny accessory ecosystem. The 11mm Dovetail to 20mm Picatinny Adapter converts that narrow dovetail to a full 10-slot Picatinny rail in one step. Now your air rifle or .22 can use the same red dots, scope rings, and bipods as your AR-15.
Key Features
- 11mm-to-20mm Conversion: Mounts onto standard 11mm dovetail rails found on air rifles, .22 LR rifles, and European sporting rifles. The top surface is a full MIL-STD-1913 Picatinny rail — compatible with all Weaver and Picatinny accessories.
- 10-Slot Rail Length: Extended 10-slot length provides enough rail space for scope rings, red dot sights, or magnifier mounts with proper eye relief adjustment range.
- Locking Grub Screws: Multiple hardened steel grub screws lock the adapter firmly onto the dovetail. The screws bite into the dovetail grooves, preventing the adapter from walking under recoil — even on spring-piston air rifles with bidirectional recoil.
- Stop Pin Included: Removable recoil stop pin engages the dovetail’s factory stop hole (where present), providing additional recoil resistance for heavy optics.
- Anodized Aluminum: Aircraft aluminum with matte black anodized finish — matches your rifle’s receiver and resists corrosion in the field.
