The Sightron Objective Stop Ring is designed to improve depth of field for all Sightron 60mm and 56mm models. In addition, it increases the mirage reading capability of the riflescope under certain conditions. This accessory comes in a two-piece model, allowing users to step down their 56mm or 60mm objective to either 49mm or 43mm, depending on the conditions. All objective stop rings are made to fit with or without a sunshade attached.

I have only used this reducer once so far. It was put on the Sightron S6 and shot indoors on a very warm day. No signs of mirage. So far so good, I love it so far.
I used it for the first time Sunday 29 March 2026 shooting F Class targets at 600 yards. The weather was mostly cloudy but when the sun peaked through with the wet ground, mirage raised its ugly head. With the new device, I was able to keep my Sightron SIII 10-50X60 set at full power and clearly see the X ring.
works great
I haven't used it yet. but it looks good.
it works
It helped with mirage
Came as ordered.
It fits and looks like it should work but have not had enough mirage to see how it works.
I have used it 3 times now and still get mirage just not sure why! Great quality of work and fast shipping
It didn’t work for me
Cuts most of the mirage so you can clearly see the target but allows some mirage through to help read the wind. I’m going to buy a second for my other SIII
Perfect fit. Well made helps reduce some of the mirage. Cleans up the Image.
IT seems to be well made
The fit was perfect and it does what it's supposed to.
Quality looks great! I haven't had the opportunity to use it yet.
I went to the range with this attached to my scope. The mirage was very heavy and the target at 600yds was dancing around. My first thought was that this wasn't having much effect on reducing mirage. Then I took it off. Wow! The difference was dramatic. Now, without it, the mirage was so bad that I had no confidence in my ability to hit the 6 inch target. I immediately put it back on and this improved the image 30 to 40 percent. A great product and I'm so glad that it was available directly from you.
Great accessories
