Overview
The Sightron SIII LR 10-50x60 is a target riflescope built around a 30mm one-piece tube and a 60mm objective lens, with a dot target reticle for long-range precision shooting rather than hunting.
This scope targets long-range and benchrest shooters who want high magnification and a fine aiming point rather than a duplex crosshair. Owners who have run it at 600 to 1000 yards describe it as repeatable, but the sample size here is small and at least one buyer flagged turret and parallax problems that others with the same brand did not have.
- 30mm one-piece tube construction
- 60mm objective lens with Zact-7 Revcoat multi-coating
- Dot target reticle for precise long-range aim points
- Waterproof and fog proof housing
Who it's for
Suits long-range target and benchrest shooters who want a 10-50x scope with a precise dot reticle for repeatable adjustments. Less suited to hunters who want a simpler duplex reticle or fast target acquisition at close range.
What buyers say
From Amazon customer reviews.
Owners who use the scope for long-range and benchrest competition called the glass clear and the adjustments repeatable, with several praising the fine dot reticle and close focus. Two reviewers had problems: one scope would not hold parallax after being set, which the buyer suspected was shipping damage, and another said the turret knob attachment made zeroing difficult.
Strengths and trade-offs
Drawn from this product's published specifications.
- High 10-50x magnification for long range work
- 60mm objective for light transmission at high power
- 1/8 MOA dot reticle liked by competition shooters
- Close focus useful for competition stages
- One buyer received a unit that would not hold parallax
- Another reported the turret knob attachment made zeroing difficult
Performance notes
The 10-50x magnification range and 60mm objective are built for stretching distance, with Sightron's Zact-7 Revcoat multi-coating aimed at keeping the image bright at high power. Reviewers using it out to 600 and 1000 yards described the tracking as solid and repeatable, which matters more than raw magnification for competition use.
