MitaPoint 11 mm to Picatinny / Weaver Rail Adapter – Long Version
This adapter is designed for shooters who want full Picatinny / Weaver compatibility on a firearm equipped with an 11 mm dovetail rail, without compromising on stability or positioning flexibility. The 260 mm length is particularly beneficial where the existing 11 mm rail is long and ample room is needed to correctly position the optic.
Construction and Materials
The adapter body is CNC-machined from aerospace-grade aluminium. The hard-anodised matte black finish is scratch-resistant, non-reflective and provides durable corrosion protection under demanding conditions. The construction is rigid and solid – a genuinely stable platform for any optic.

- Locking screws — 6 × high-strength hex screws
- Weight — 162 g
- Package contents — adapter, hex key
Mounting Solution
Six high-strength hex screws clamp the adapter firmly to the 11 mm rail. The integrated stop pins prevent the optic from shifting longitudinally under recoil or bidirectional vibration – particularly important on spring-powered airguns, where the characteristic double-stroke recoil pulse can loosen conventional mounts over time.
When Is This Adapter the Right Choice?
- Your existing 11 mm rail is long — and you want to use the full surface area for secure clamping
- You are mounting a larger or longer riflescope — where greater freedom is needed to dial in the correct eye relief
- You use Picatinny-standard mounts — and the existing 11 mm rail does not support them directly
- You are working with a spring-powered airgun — where enhanced vibration resistance is essential
Who Is This Adapter For?
Recommended primarily for airgun shooters and .22 LR platform users whose firearm features an 11 mm dovetail rail but who wish to run Picatinny-standard mounts for their riflescope or other optical accessory. The long version is especially well suited to PCP and spring-piston air rifles, where precise scope positioning and reliable, vibration-proof mounting are both essential requirements.
