Sightron SIII Competition 45x 45mm Target Dot 1 Reticle Rifle Scope Review

My first impression of Sightron SIII Competition 45x 45mm Target Dot 1 Reticle Rifle Scope

For over a decade, I’ve been immersed in the world of optics, from outfitting weekend warriors to advising competitive shooters. When the Sightron SIII Competition 45x 45mm Target Dot 1 Reticle Rifle Scope landed on my workbench, I knew I was handling something special. Sightron has a reputation for quality, and this scope promised precision, clarity, and unwavering performance for serious target shooters.

I was seeking a scope that could truly deliver at extreme distances. My previous scope, while good, lacked the fine-tuned adjustments and clarity needed for consistent sub-MOA groupings beyond 500 yards. The immediate impression was one of robust construction and thoughtful design, hinting at the quality I hoped for in demanding competitions.

Unboxing the Sightron SIII Competition 45x 45mm Target Dot 1 Reticle Rifle Scope revealed a sleek, matte black finish. The weight (20.5 oz) felt substantial, suggesting durable internals and solid build quality, while the target-style turrets looked precise and easily resettable. Compared to my Vortex Viper PST Gen II, this Sightron felt more purpose-built for pure target shooting, sacrificing some versatility for optimized long-range precision.

My initial excitement stemmed from the promise of unparalleled clarity and the super-fine .1 MOA dot reticle. Was I excited? Absolutely. This scope seemed poised to elevate my long-range game, provided it lived up to the hype.

Real-World Testing: Putting Sightron SIII Competition 45x 45mm Target Dot 1 Reticle Rifle Scope to the Test

First Use Experience

My first test involved a precision rifle competition held at a local range known for its challenging wind conditions. I mounted the Sightron SIII Competition 45x 45mm Target Dot 1 Reticle Rifle Scope on my custom-built .223 bolt-action rifle, carefully bore-sighting it before dialing in the zero at 100 yards. The wind was gusting from left to right, making consistent shot placement difficult.

Despite the challenging conditions, the Sightron’s exceptional clarity and fine reticle made target acquisition and holdover corrections surprisingly manageable. Adjusting the parallax with the side focus knob from 10 yards to infinity, allowed me to quickly optimize the image at varying distances. The 1/10 MOA clicks were crisp and repeatable, allowing for precise adjustments even under pressure.

My main concern was the extremely high magnification (45x). In anything less than ideal light, that much magnification can be detrimental, but that wasn’t the case here.

Extended Use & Reliability

After several months of regular use, including weekly range sessions and another two competitions, the Sightron SIII Competition 45x 45mm Target Dot 1 Reticle Rifle Scope has proven remarkably consistent. The finish shows no signs of wear, despite exposure to varying weather conditions. The turrets maintain their positive clicks, and the zero has remained rock solid.

Maintenance is simple: a quick wipe-down with a microfiber cloth after each use keeps the lenses clean and clear. Comparing it to my older Leupold VX-3i, the Sightron offers a noticeably brighter and sharper image at extreme magnifications, enhancing target identification and reducing eye strain. This scope is truly built for serious competition.
