Leupold 183551 Window Mount Clamp - Black Optics Support System

The Leupold 183551 Window Mount Clamp delivers rock-solid optic stability for vehicle-based observation and precision shooting applications. This black-finished mounting system transforms any vehicle window into a stable shooting platform, eliminating the shake and movement that compromises accuracy during extended surveillance or hunting sessions.

What Makes This Different

Unlike generic window mounts that rely on suction cups or flimsy clamps, the Leupold 183551 features a precision-engineered clamping mechanism that distributes pressure evenly across the window surface. The system maintains zero shift even during recoil from high-powered rifles, while the quick-release design allows for rapid deployment and storage. Professional-grade construction ensures consistent performance across temperature extremes from -40°F to 160°F.

Key Features

• Precision-machined aluminum construction with corrosion-resistant black anodized finish
• Universal window compatibility fits glass thickness from 0.25" to 0.75"
• Quick-release lever system enables one-handed operation and rapid setup
• Integrated vibration dampening reduces scope movement by up to 85%
• Standard Picatinny rail interface accepts most optic mounting systems
• Non-marring contact surfaces protect vehicle glass from scratches
• Compact folding design stores in standard range bag or glove compartment

Field testing demonstrates exceptional stability across various vehicle types, from compact cars to full-size trucks. The mount maintains consistent point of impact during precision rifle work, while hunters report improved success rates on long-range shots from elevated positions. Weather sealing protects internal mechanisms from moisture infiltration during extended outdoor use.
