Lyman 66 Receiver Peep Sight - Adjustable Iron Sight Black

The Lyman 66 Receiver Peep Sight delivers precision iron sight performance for classic rifles and modern sporting firearms. This adjustable rear sight system provides shooters with enhanced accuracy and target acquisition capabilities over standard factory sights.

What Makes This Different

The Lyman 66 features a robust receiver-mounted design that positions the rear sight closer to the shooter's eye, creating a longer sight radius for improved accuracy. Unlike basic notch and post configurations, this peep sight system allows for faster target acquisition while maintaining precise shot placement. The windage and elevation adjustments offer repeatable settings with audible clicks for consistent performance.

Key Features

• Receiver-mounted peep sight for extended sight radius and accuracy
• Windage and elevation adjustments with positive click detents
• Durable steel construction with corrosion-resistant black finish
• Compatible with most bolt-action and lever-action rifles
• Multiple aperture options for varying light conditions
• Tool-free windage adjustments for field corrections
• Low-profile design maintains rifle balance and handling

Field performance shows marked improvement in accuracy over factory iron sights, particularly at distances beyond 100 yards. The peep sight configuration naturally centers the front sight post, reducing alignment errors common with open sights. Hunters appreciate the quick target acquisition in low-light conditions, while competitive shooters benefit from the consistent sight picture and repeatable adjustments.
