Convert 11 mm dovetail to 21 mm Picatinny rail — more accessories for your air rifle

A simple and functional adapter that allows you to mount accessories intended for 21 mm Picatinny/Weaver on air rifles with 11 mm dovetail. Perfect when you want scopes, red dot sights, mounting rings, or other accessories that are normally used on airsoft and live firearms with a 21 mm rail — larger selection, more options. The product is made of lightweight and durable aluminum and comes with mounting screws for easy installation.

Features and benefits

  • Conversion: Converts 9–11 mm dovetail to standard 21 mm Picatinny rail (Weaver-compatible).
  • Material: Aluminum for low weight and good durability.
  • Compatibility: Fits most air rifles with 11 mm dovetail.
  • Easier upgrade: Mount red dot sights, laser sights, sight rings, or scopes that normally require a Picatinny rail.

Installation tips

  • Clean contact surfaces before installation so the adapter sits evenly.
  • Torque tighten the screws gradually and evenly — do not overtighten. Feel free to use a mild thread locker to prevent the screws from loosening over time if the weapon receives shocks or similar.

Who is the product suitable for?

This adapter is suitable for those who want to increase the compatibility of an air rifle — for example, mount red dot sights, sight rings, or other Picatinny accessories that do not fit directly on 11 mm dovetail. The range of accessories for 11 mm dovetail is significantly smaller than for the standard 21 mm Picatinny rail.

Briefly about the difference

11 mm dovetail is standard on many air rifles but limits which accessories you can use. Picatinny/Weaver (21 mm) is leading for accessories for live firearms as well as airsoft and provides a larger range of sights and accessories — with this adapter you simply get access to more products and easier mounting solutions.
