Works great with our fiber optic front sights: Marlin front sights and Henry front sights for a super fast 3 dot system like a pistol (Super Bright and Robust!)

In the Package: All 22 RIMFIRE lever-action peep sights come with one sight base w/windage screw, one aperture spring w/ elevation screw, four set screws, two Allen wrenches.

Note: Cloverleaf Ghost apertures have the four scope-like points + fiber optics and are open .165" and do accept our screw in peep apertures. "Clover leaf groups" precision put our RPP CloverLeaf Receiver Peep Sights in a class by themselves. Bright fiber optics (left/right of the Cloverleaf aperture) paired with an RPP front fiber optic sight, creates a super fast three-dot sighting system similar to a pistol.
