GS3 4-20x50 Reviews

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. 

Asked by: Wini
0.00 = crosshair 1.49 = 1st tick 4.31 = 2nd tick 7.18 = 3rd tick 10.56 = 4th tick all measurements are MOA from center

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?

Asked by: PS2014
For the objective lens you will need a size 43 scope cap, for the eye piece you will need a size 20. You can find more on their product information for these on their web site here: http://www.butlercreek.com/productsImages/charts/flip_scope_chart.html

Can these hold up on a 338 Lapua. Or would you recommend different.

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!

Asked by: Eric J
The subtensions of the reticle will vary between the S1 and S7. For specific measurements please contact customer support at 888-228-7747 and they can provide you with the subtensions as well as advise what the hash marks will indicate in yards.

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.

Asked by: Eric J
The reticle is accurate at maximum magnification. We do not manufacture a sunshade for the GS3 riflescope.

Does Steiner offer custom turrets or dials for their scopes? 

Asked by: ZB22B
We do not offer custom turrets or dials at this time.
Answered by: SteinerCustomerService
Date published: 2016-07-14

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".

Asked by: Ted S
14.9 is the correct length.

How does your resettable zero work

Asked by: Gunner50
The index ring (with all the numbers and hashmarks on it) has a little notch cut out of the bottom edge. Use a toothpick or other small tool to push the ring around the circumference of the turret until the '0' is aligned with your guide mark on the body of the scope
