11mm to 20mm Picatinny Rail High Adapter - 14 Slots

This adapter converts a classic 11mm dovetail rail to a standard 20mm Picatinny / Weaver rail. It is designed for weapons that have a factory 11mm rail, but you want to use Picatinny compatible optics, mounts or accessories.

Technical data

• Total length: 174 mm
• Dimensions: 174 × 21 × 21 mm
• Weight: 64 g
• Number of slots: 14
• Upper rail standard: 20 mm Picatinny / Weaver compatible
• Bottom mount: 11 mm dovetail
• Material: aluminum alloy
• Surface treatment: anodized black
• Manufacturing technology: CNC machining

Design and function

The 174 mm long body provides 14 mounting slots, so the position of scope rings, single mounts or other Picatinny compatible accessories can be freely adjusted. The length allows for precise adjustment of eye relief even for riflescopes with longer tubes. The 21 mm upper rail is Picatinny / Weaver standard, so it is compatible with most modern optical mounts. The adapter is high-profile, meaning it raises the position of the optic compared to the original 11 mm rail of the weapon. This can be an advantage in the case of a larger objective diameter or if more free space is required due to the design of the bolt mechanism or barrel.

Material and processing

The adapter is made of aluminum alloy, CNC-machined. This ensures:

• precise rail geometry
• parallel surfaces
• proper fit to an 11 mm dovetail rail

The anodized surface is more wear-resistant than the painted version and does not shine. The 64 gram weight is considered light in its category, so it does not unnecessarily burden the weapon, especially in air rifle or .22LR configurations.

Area of ​​application

• air rifles (with 11 mm rail)
• .22LR weapons
• hunting and hobby shooting applications
• weapons where Picatinny compatibility is required from an 11 mm rail

Not a solution optimized specifically for high-recoil, strong centerfire calibers, but for typical airgun and rimfire environments.

Important information

This is a conversion rail, not a simple narrowing insert. The full-length rail changes the height of the optic and the geometric adjustment of the weapon. After installation, it is advisable to re-shoot and zero the system. If you need a stable, long and multi-position mounting option for 11 mm → Picatinny conversion, this is a simple and correct technical solution.
