Let's Talk About the Scope in Details:

5x Zoom Range:

If we go through the specifications chart, first of all, we can observe the exclusive 5x zoom range. The 5x Zoom range can render sharp resolution at long distances. Thus, you don’t have to worry about how far your target is. You can get the accurate shooting in wide-open areas.

So, now get your favorite centerfire, rimfire or muzzleloader rifle and pair them with this fabulous scope to facilitate long-range shooting.

CAT ™ Color Adjusted Transmission:

Moreover, CAT is actually lens coatings that are renowned as game sensing feature which makes it easier to spot game in any environment. Once I watched an ox cross a field in the evening through it before I mounted it on a rifle and the contrast was up to the mark. So, this feature has made it worth it.

This one is the most lucrative feature from the heaps of features. This has made Steiner scopes stand out from others. CAT magnifies contrast to visually separate our prey from its surroundings that are either leafy or shadow dappled.

Steiner Plex S1/ S7 Reticles:

If we look next in the chart of specifications, we can see the GS3 models with an A4 reticle or the Steiner Plex S1/S7 versions. The S1 reticle assists you in fixing holdover for distance and compensating for wind & bullet-drop compensating reticle which is not overly complicated or cluttering the sight window.

So, from the Steiner gs3 review, we get that the Steiner gs3 2-10×42 or 4-20×50 or 3-15×56 scope is definitely an excellent scope with S1 reticle.

A4 Reticle:

Furthermore, there is another type of reticle. This is A4 reticle which sits in the second focal plane and gives a simple, uncluttered aiming tool. So, the various models of Steiner scope have both stout and compact design actually, don’t they?

Short Mounting Length:

When we look at the chart, we can see that this scope bears just 5.4 inches short mounting length which is compatible with lightweight mountain rifles, muzzleloaders or firearms.

So, the adjustments are so accurate that you will fall in love with this tiny masterpiece.

Built-in System:

This scope is going up with flying colors for its robustness and supreme construction. For durability, this scope is made of solid aluminum without any welds and seams.


This 13.5 inches and 18 ounces scope is filled with lots of captivating aspects. The rugged tube is filled with nitrogen to set off its unwavering and all-weather performance. So, count on this beast for your memorable journey in any cold and wet condition.

Windage & Elevation Range:

The capped turrets provide 48 MOA of windage adjustment. Again, the elevation adjustment is quite 64 MOA. So, the maximum range is 70 MOA with ¼ MOA per click which offers precise adjustment for wind and trajectory.

The company has gained confidence by producing and offering a huge amount of scopes to armed forces all around the world. The company always keeps an eye on high-quality manufacture, customers’ satisfaction.

So, its heritage warranty ensures commitment, repair or replacement of any equipment without any cost. You will get new components without any warranty card.

Frequently Ask Questions

In this Steiner gs3 review, we explore that “An MOA is 1/60th of a degree or it is about 1 inch at 100 yards. This is used as a standard unit and easily measured. So, if the adjustment is 60 MOA, your scope will move a single degree on a circle.

Actually, these terms are like ancestors. They had been used from the past and has become the standard. The adjustments are actually horizontal and vertical. Currently, these terms are – adjust the reticle left or right to compensate the wide and adjust the elevation knob by elevating your bore in relation to the optical sight.

This sounds tough but actually, it is not. It is the shift the reticle to your eye or apparent reticle movement. It happens if there is an improper alignment of the scope with the eye. Too much distance between your eye and the ocular lens can occur parallax. So, move your head back and forth and you will find a place of parallax free.

There is no exact answer to this ques. The main thing you need to keep in mind that the objective lens should be matched to the magnification of a scope.

Final Words

In summary, I would like to say that, “you can conquer your prey & brag your success by using this scope.”
