Overview
A first-focal-plane rifle scope with 2.5-20x magnification and a 50mm objective, built for hunters who need a compact optic that holds up in extreme conditions. Ships with Tenebraex flip-up covers, a cleaning kit, a multi-tool and a power throw lever.
Nightforce sits at a premium tier against brands like Leupold, and reviewers who own both confirm the glass and mechanical repeatability justify the step up, if not proportionally to the price gap. The FFP MOAR reticle scales with magnification so holdovers stay accurate at any zoom setting.
- 2.5-20x50mm first focal plane optic
- ZeroStop elevation adjustment
- Optional integrated power throw lever
- MOAR illuminated reticle
Who it's for
For hunters and long-range shooters who already run higher-end optics and want a compact 8x zoom scope for one rifle setup. Casual shooters on a budget will find more affordable glass elsewhere in the Nightforce lineup.
What buyers say
From Amazon customer reviews.
Owners consistently praise the glass clarity and how well the scope tracks and holds zero, with several directly comparing it favorably to Leupold. The one recurring gripe is that a battery was missing from the box on at least one unit, despite the price tag.
Strengths and trade-offs
Drawn from this product's published specifications.
- Crisp glass reviewers compare favorably to Leupold
- ZeroStop makes returning to zero repeatable
- Compact 8x zoom range in a rugged package
- Ships with flip-up covers, tool and manual included
- Battery not included in at least one shipment despite the price
- Costs multiple times more than comparable Leupold glass
Performance notes
The ZeroStop elevation dial lets you return to a set zero after dialing for distance, which matters when you take a long shot and then need to come back to a known baseline quickly. The optional integrated power throw lever gives a visual and tactile reference to current magnification.
