Overview
The Nightforce NX6 3-18x50mm F1 is a first focal plane riflescope with a 50mm objective and exposed FieldSet turrets, positioned for mid to long range hunting, tactical and precision shooting.
This model sits between the wider 1-6x and 6-36x NX6 scopes in the lineup, aiming at shooters who want more reach than a close-range scope but do not need the extreme zoom ratio of a dedicated long range setup. The 30mm tube is lighter than the 34mm tube on the higher-magnification NX6, which fits its middle-distance positioning.
- 3-18x first focal plane magnification
- 50mm objective lens
- 30mm main tube
- DigIllum illumination with 5 brightness levels and memory recall
Who it's for
Hunters and shooters who need reliable mid to long range performance without the size of a dedicated long range scope. Shooters who need extreme magnification for very long distances should look at the higher-power NX6 F1 model with the 34mm tube instead.
Pros and cons
- 3-18x first focal plane range for mid to long distance
- 50mm objective for a brighter low-light image
- Exposed FieldSet turrets for repeatable tracking
- Lighter 30mm tube than the higher-power NX6
- No published rating or review data available
- Exposed turrets can be bumped out of position if not guarded during transport
Performance notes

DigIllum illumination offers red or green lighting with five brightness levels and memory recall of the last setting.
