This is ONLY the base for our rear sight blades. You must order your preferred blade style separately.

Fits any picatinny rail or standard 10/22 optical base.

Installs easily with 2 non-marring, flat bottom set screws.

Can be placed toward the front of your rail to make the ring smaller in relation to the front sight or placed toward the rear of the rail to make the ring larger.

Use with our SOL Fiber Optic Front Sights or your own front sight.

Center of rear sight base is .600" above the top surface of the Picatinny Rail and has 0.150" of adjustment up and 0.150" down.

    Fits right on a short rail on my 10/22 build. Very nicely machined part.

    This rear site base worked well for me setting up an PCCI. Yes, I would recommend! :)

    I am going to review all three products together, because they belong together. The rear sight base for a picatinny rail, priceless. Just add either the peep or open option (your preference) and vola, your open gun is now an iron sight gun. I wonder why no one has come out with this before. It is a 5 star addition to any open rifle

    Need to have more up and down adjustment. But it is still a great sight

    Bought the peep sight with this and it works great. not much room for windage, but having proper and same check placement every time, makes it work perfectly.

    Rear sight base.

    I love these sights!!! A good friend of mine bought a set of these sights and after seeing them on his gun I had to have a set so I ordered a barrel and sights. Super fast shipping and Wiland has great customer suport. “The best in the business” the sights mount to a standard 10/22 base and they are amazing. The gun come right up and point of aim is on. This is the closest thing you will find to a red dot sight in iron sights. You just put the red fiber optic on the target and center of the rear sight window and it’s dead on. Most adjustment I have ever seen on iron sights. I just can not say enough good about them. But it you will not regrets it.
