Rear Sight Replacement

When individual parts from complex rear-sight assemblies go missing, they can be hard to replace because of proprietary features such as thread specifications. One example: the tube-fed, bolt-action Marlin 81 DL’s rear target sight assembly shown here can cost more than the gun itself, and its aperture is often lost.

That’s where Apertures ’N’ More steps in—producing replacement apertures to order and offering aperture adapters, replacement sight parts and screws for hard-to-find models. Offerings include apertures for the following brands: CZ, Lyman, Marbles, Mossberg, Parker-Hale, Redfield, Remington, Thompson/Center and Winchester.

The MSRP is $11, as shown (varies by item and model). For more information, visit aperturesnmore.com.
