Hover to Zoom
The Steiner GS3 “game sensing” scope utilizes exclusive CAT (color adjusted transmission) lens coatings to amplify contrast in the peak human vision sensitivity range. The optimized contrast effectively separates game from leafy or shadow-dappled backgrounds, exposing your target to a clean, accurate shot. And the GS3 5x zoom range lets hunters from eastern whitetail country to western big game ranges pair their new scope with their favorite centerfire, rimfire or muzzleloader rifle. And or course, Steiner’s bedrock reliability will always deliver unfailing performance, whatever firearm or target you prefer.
Versatile enough for prairie dogs, big game or the bean field.

Is there a reliable place I can go to get the subtensions for the S-1 reticle? I have the GS3 4-20 and need to know the measurements for thereticle. I have tried tech support and info@steiner-optics with no luck.
I would like to put Butler flip-up scope caps on my GS3 4-20x50. Could you tell me what size caps would fit this scope?
Hi! Two questions. I will be mounting it on a Sig SSG3000. Do you have any recommendations re: rings? Can one estimate range with the reticle hash marks? I.e. how many inches from the first elev. mark from zero at 100, 200 yds etc? Thanks!
Not a big deal for me but does this scope have threads for anti-glare or sunshade attachments? Also, at what magnification levels are the S1 reticle accurate at? I couldn't find the reticle user guide mentioned in another answer.
Does Steiner offer custom turrets or dials for their scopes?
1. Why don't you offer this scope with dial turrets - it would make it an excellent LR Mountain scope. Not real useful without this option. Can you purchase after market turrets? 2. What is the length - you show both 14.9" and 16.4".
How does your resettable zero work
Would I have any issues mounting this optic on long actions? 240 weatherby / 30-06 spr both are weatherby vanguard rifles.
