Aperture sight for Marlin 22?

[Caseless]

I finally bought a bolt action 22LR rifle. A Marlin 925R. I prefer not to use scopes for short range rifles. Does any company make an aperture rear sight for it?

Williams makes an aperture sight for .22 rifles that fits on the grooved receiver most of them have.

I put one of those on my Remington 581-S and I am very happy with it. Installed in a minute and is easy to adjust.

I need a taller front sight to shoot at 50 yards, however, so also be aware of that.
