Wiland USA Modular Rear Sight Base


Please select a Rear Insert from our Rear Sight Insert selection for 10-22 or PCC.

(Please Note: PCC Inserts are much taller to accommodate the difference of comb height on AR pattern rifles)


Fits any Picatinny Rail


Installs in about 1 minute with 2 non-marring, flat bottom set screws.

Move your Rear Sight forward to make it smaller in relation to the front sight or move it toward the rear of the rail to make it larger.

Everyone is different and has different eyes and needs.


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

Center of Rear Sight is .600" above the top surface of the Picatinny Rail and has .150" of adjustment up and .150" down.

If you have a particular Rear Insert in mind, let us know !

    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.

    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.
