11mm Dovetail to 20mm Picatinny Rail Adapter – 175mm Cantilever Mount for Prism Scope & Night Vision
Built for Larger Optics. Engineered for Precision.
When you're running a prism scope, night vision device, or any long optic on an 11mm dovetail rail, you need a mount that can handle the extra length and weight without flexing. This 175mm cantilever-style adapter delivers a rock-solid Picatinny platform with 14 slots of positioning flexibility — and a 0.7" low-profile rise that keeps your sight line exactly where it should be.
