11mm Dovetail to 20mm Picatinny Rail Adapter | Non-Riser Snap-On Clip | 4 or 9 Slot

Convert Your 11mm Dovetail to Picatinny in Seconds — No Tools, No Riser

Your .22 or airgun has a perfectly good 11mm dovetail rail — this adapter unlocks the entire Picatinny accessory ecosystem without adding any height. The spring-tension snap-on design means you can mount and dismount in seconds, while the detachable stop pin keeps everything locked in place once you're set up. Choose the 4-slot version for a compact, lightweight fit, or the 9-slot version for maximum optic positioning flexibility.
