More from this brandAll Leupold rifle scopesOverview
A 1-4.5x24 second focal plane rifle scope with a 30mm tube, illuminated FireDot TMR reticle and Motion Sensor Technology that shuts the illumination off after five minutes of stillness. Built as a low-power variable optic for close to mid-range work.
Leupold pitches this as a professional-grade optical system with glare reduction for harsh direct light, machined and assembled in the US. One buyer's report of receiving a different brand's scope inside a genuine Leupold box is worth flagging, since it points to a packaging or seller issue rather than the optic itself.
- 1-4.5x24 zoom on a 30mm tube
- Illuminated FireDot TMR reticle
- Motion Sensor Technology auto-off
- Glare-reduction optical coatings
Who it's for
Hunters and shooters who want a true low-power variable scope for fast target acquisition at short range with some reach out to mid distance. Less suited to long-range precision shooters, who should look at Leupold's higher-magnification Mark 4HD models.
Pros and cons
- Illuminated FireDot TMR reticle for fast target acquisition
- Motion Sensor Technology conserves battery between uses
- Machined and assembled in the USA
- Waterproof, fogproof and shockproof
- Second focal plane limits holdover accuracy to max zoom
- At least one buyer received a different brand's scope inside the box
Performance notes
Motion Sensor Technology automatically powers down the illuminated FireDot reticle after five minutes without movement and reactivates instantly once the scope moves again, which is meant to extend battery life between hunts. The second focal plane design keeps the reticle a constant size through the 1-4.5x zoom range, favoring fast aiming over holdover precision at low power.
