Mossberg Receiver Sight Aperture Disc – Fits Models 46B, 144, 146, 151 – Vintage

If you’re restoring a vintage Mossberg or just need a replacement aperture disc, this is the part you’re after.

It’s designed to fit Mossberg receiver sights on models like the 46B, 144, 146, and 151.

It’s brand new old stock—meaning it’s never been installed, just been sitting around waiting for the right project.

The disc is the part with the small hole you look through to line up your shot, so if yours is missing or damaged, this drops right in.

Classic Mossberg quality, made for the old-school rifles.

Whether you’re a collector or just keeping an heirloom shooter in working order, this little disc is exactly what the doctor ordered.
