Customers are mixed about the transparency of the rings. Some mention that they can still see the iron sights through the bottom, while others say that they blocked the actual viewing of the open iron sight. The see-through height is not quite enough to use the iron sight, and the rings did not give option for open sight.

They work
I needed them to get a vortex crossfire s cond focal plane scope on. 22 lr semi auto. And a 22 wmr . They needed to be high enough for the bolt handle to clear the scope . And for the 22 lr semi automatic to eject property. This is a 200 yard shot with the lr . Which means with a 100 yards zero . The bullet drops 36 inches . I needed these scope rings to make it happen.they worked . I saw other reviews where people did the worked the way loose . I haven't noticed it I've fired ,500 rounds or there about . I used blue medium locktite. And torqued to 18 in lbs ,I doubt they are going to slip .

5.0 out of 5 stars Great scope rings for the money!
Reviewed in the United States on November 13, 2022
Style Name: High ProfileVerified Purchase
I used these scope rings to install a 3-9x40 on my 22 bolt action rifle. They are made of quality aluminum, and were free from any manufacturing defects that I could see. They mounted easily on the dovetail, and hold securely.

I got these rings so I could use the iron sights and the scope on my rifle, and they work wonderfully for that purpose. I would advise that you want to make sure you have an adjustable height cheek rest to make sure you get a proper cheek weld.

The only "downside" I can find (though it is a minor inconvenience) is that they use a torx screw, not a hex head. So you need to make sure to keep track of the tool that comes with it, unless you have a torx set, or a screwdriver kit with multiple heads. I usually prefer torx head screws for other uses, but not a huge fan on machine screws. However, you should be able to run to your local hardware store and get some hex replacements for next to nothing.

Pros:
-Cost
-Build
-Allows use of iron sight

Cons:
-Torx screws
