Leupold 182417 Pro Gear Quick-Stem Adapter 4.5" Black Aluminum

The Leupold 182417 Pro Gear Quick-Stem Adapter delivers rapid mounting capability for spotting scopes and other optical equipment in field environments. This 4.5-inch aluminum adapter transforms standard tripod setups into quick-deployment systems for tactical and hunting applications.

What Makes This Different

Unlike fixed mounting systems, this quick-stem adapter features Leupold's proprietary locking mechanism that secures optics in seconds while maintaining zero repeatability. The 4.5-inch length provides optimal height clearance for most rifle configurations and shooting positions. Machined from aircraft-grade aluminum, it weighs 40% less than comparable steel adapters while delivering superior corrosion resistance.

Key Features

• Quick-release stem mechanism for rapid optic deployment and removal
• 4.5-inch black anodized aluminum construction resists wear and corrosion
• Compatible with standard 1/4"-20 and 3/8"-16 tripod threads
• Precision-machined surfaces ensure consistent optic alignment
• Lightweight design adds minimal bulk to field gear loadouts
• Textured grip surfaces prevent slippage during manipulation
• All-weather performance in temperatures from -40°F to 160°F

Field performance centers on the adapter's ability to maintain optical alignment through repeated mounting cycles. The spring-loaded locking collar engages with positive tactile feedback, eliminating guesswork during low-light operations. Hunters appreciate the silent operation that won't spook game, while competitive shooters rely on the repeatable zero return for stage transitions.
