Elevation problem 4/14/2021
After installing the sights my Mark IV Target shoots 2 inches high with front sight elevation lowered all the way to the maximum. I like everything else about the front and rear sights, but this is obviously an unacceptable situation. I have not yet contacted River for possible support but will be doing so.

Does not fit 2/23/2019
The “v” notch rear sight blade doesn’t fit mark 4 target.
poor quality rear sight 8/4/2018
Front fiber sight is okay. Rear sight poorly manufactured. White line doesnt line up with notch, which makes sighting confusing. Even worse, the rear sight runs out of adjustment before its tuned in perfectly. Im getting different sights. These are junk.

So Worth The Money 7/8/2017
Makes it super fast and easy to line up the sights with the target, especially with the v-notch.
Great sight 4/10/2017
Installing the front sight is simple but the rear sight is tricky. When taking out the old rear blade, make sure to capture the spring behind the blade. An instruction sheet would go a long way here.

wrong part for mark 3 competition 4/23/2015
Ordered this after discussion with rep. Upon receipt, was apparent it was NOT for a mark 3 competition model handgun. Called customer service who insists it is the correct part despite the dovetail that will not sit inside the non-existing mate in the barrel or the package that states it is for a 10/22 rifle.

Easy sight alignment 12/17/2014
I like the v-notch rear and hiviz front sights that came with my Hunter model. Since this was the first I used this type of sight it took me about 4 magazines to get use to it. After that I was putting rounds in a 2 inch circle at 25 yards consistently.
