GS3 4-20x50

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.

GS3 4-20x50 is rated 4.5 out of 5 by 6.
Rated 5 out of 5 by from Best for the money! Just bought this scope at Easthill Outdoors in Ont. Canada, my favourite shop. Put it on a Sako Finnlight 270 WSM, with Optilock bases and extra low rings and took it to the range. It's mid January at -20C with a good wind and shot 5 quarter sized groups at 200yds. I can't wait to try it at longer distances. Great package, awesome products!

Rated 4 out of 5 by from Features are great ergonomically, although magnification knob is very stiff and pulls you off target. Could also use a longer eye relief. It has served me well in both Africa and here in North America. The 50mm allows for quick target acquisition. Optics are crystal clear. l

Rated 5 out of 5 by from Get what you pay for. I have wanted one of these scopes for years but could not get over the price point in my budget. A local store of mine ended up having a clearance sale on Optics so with $350 off.. I could finally buy one and justify the money. The scope is just as clear and nice as you would expect from Steiner or most German scopes. Highly recommend it.

Rated 4 out of 5 by from Excellent value I purchased this for a Remington 700 in 7mm mag. I choose the S-7 retical because it is designed for 22-250 which has very similar ballistics up to 700 yards. The scope was in perfect shape at delivery. The eyebox is very generous at all but the highest magnifications, and even then maybe more forgiving than some of my other brands. Very good clarity and focus, very good brightness and only average low light visibility. I wish I could have afforded the night hunter series. The focus ring is rubber wrapped and a little too stiff. My rubber ring will bunch up out of position while adjusting in one direction. I may try adding some adhesive under the loose spot. I talked with customer service with a few questions before I purchased and they were great. They gave me ring and mount options and part numbers and I took there advice and everything fit fine with this large scope. I asked about the glass and they did state that it was apochromatic only, not achromatic. I still don't know the exact origin of the lenses but I would like to. This scope has the thirty mm tube and a large ocular end so it does have a very easy, relaxed view, and despite the apochromatic glass I don't see much chromatic aberration at all. The warranty is second to none in this industry.

Rated 4 out of 5 by from Quality Product Purchased a few weeks ago for a new rifle build I am working on. The clarity is great compared to most everything in it's price range. I am mounting on a 1 pc rail so the lack of mounting surface was no issue. It tracks well and runs a box test like a dream assuming you take the time to do a proper install. Clicks are crisp to the feel and light but audible to the ear. It's heavy but not excessive and for most of my purposes a non issue.

Rated 5 out of 5 by from Excellent scope Best purchase I ever made. The glass is as clear as it gets and the feel is just great the absolute prefect hunting scope for northeast PA.

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

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.
