The Meprolight Back Up Sights Blank Rear co-witness backup sight gives you a fighting chance when your primary optic goes down.

Meprolight's reputation for rugged durability means this sight will hold zero through heavy use and abuse.

It's light, low-profile, and doesn't clutter your gun when you're using your optic. Install it and forget about it—until the day it saves your shot.

Frequently Asked Questions

What does co-witness mean on a backup sight?

Co-witness means the sight is mounted at a height that allows it to align with your primary optic (like a red dot or scope). If your primary optic fails, you can look through the backup sight and shoot with the same sight picture—no major shift in aim point.

Do I need a front sight to go with this rear backup sight?

Yes. This is a blank rear sight and is designed to work as part of a backup iron sight system. You'll need a compatible Meprolight front sight to complete the setup.

Will this work with any rifle?

This rear backup sight is built for direct mounting, but compatibility depends on your rifle's receiver and any existing rail space. Verify compatibility with your specific platform before purchase.
