This molded, impact-resistant Lead & Steel LBUS Polymer sight set is affordable & dependable.

Don’t let the price tag fool you!

This is a reliable set, guaranteed to hold zero, shot after shot.

Skip the Amazon garbage & get something that you can rely on without breaking the bank (they are backups, after all!).

Windage & elevation adjustment doesn’t need any special tools. Just like the dials used to adjust POI, the detents that secure the sights in the upright position are steel-reinforced.

For reference, overall footprint is similar to MAGPUL MBUS.

We’re really proud of these!

    Very satisfied with my purchase, they seem very durable and I tend to be harder on my guns than I’d like. A good alternative to mbus and at a great price point.

    These back up sight are perfect for a budget build, they hold zero really well and are lightweight to boot!

    Extremely solid feeling and has no play whatsoever. I didn’t expect much when I ordered them but they feel better than my other polymer sights and they also sit lower on the rail, no space between the sight and the rail. Dare I say best polymer back up sights for the money out there? can’t just yet gotta go shooting with them first but first impressions are great.

    These work as back-up sights but I’d plan on getting something more for a primary optic. Mine had a little bit of loose plastic shavings in the diopter on arrival. Super easy to install, no play once it’s on, and holds zero well. Feels sturdy for a polymer sight. Picking up the front sight is a bit more difficult on follow-up shots than I was expecting, but I’m sure that could be improved with a little bit of light-colored paint on the post – I just wish it were a little thicker. Overall 3/5 comparable to Magpul MBUS.
