Steiner GS3 – Get a clear advantage of a “game sensing” scope that separates game from its background.

Steiner GS3

Using Colour Adjusted Transmission (CAT) lens coatings, the Steiner GS3 amplifies contrast in the peak human vision sensitivity range. This optimised contrast effectively separates game from leafy or shadow-dappled backgrounds, exposing your target to a clean, accurate shot. The GS3’s 5x zoom range lets deer to big game hunters pair their new scope with their favourite centrefire, rimfire or muzzle loader rifle. And of course, Steiner’s bedrock reliability will always deliver flawless performance, whatever firearm or target you prefer.

The GS3 series includes:

Offers a wide field of view making it easier to find your target.

For low light performance that mounts on most rifles without extra-high rings.


Gives varmint and hog hunters sharp images at night and in dim light.


Versatile enough for prairie dogs, big game or the bean field.


New 5x zoom range
Provides sharp resolution at long distances for more accurate shooting for wide open areas.

CAT Colour Adjusted Transmission
Amplifies contrast in the peak human vision sensitivity range, to spot game in any environment.

Steiner Plex S1 reticle/S7 reticle
The Plex S1 reticle helps determine holdover for distance and cascading dots/lines compensate for wind. (S7 Reticle also available on GS3 4-20×50.)

Short mounting length
Just 13.7cm for mounting on short actions, muzzle loaders or lightweight mountain rifles.

Rugged 30mm tube
Milled from solid aluminium stock so there are no welds or seams, for greater strength and durability.

Durable construction you can trust to stand up to any cold or wet condition.
