Midwest Industries Combat Fixed Rear Sight - Aluminum Black Tactical Rear Sight

The Midwest Industries Combat Fixed Rear Sight brings proven A2 sight geometry to a modern, lightweight package. If you're running an AR-15 with a flat-top receiver and want a reliable backup to your optic—or a primary sight system—this aluminum rear sight delivers the familiar sight picture that generations of shooters have trusted, wrapped in a stronger, more durable housing than mil-spec irons. Whether you're building a patrol rifle, setting up a dedicated 3-gun gun, or just want to add a quality backup system to your current setup, a dependable fixed rear sight is the foundation of any irons-only or optic-plus-irons platform.

Machined from 6061-T6 billet aluminum and hardcoat-anodized for corrosion resistance, the Combat sight is built to handle hard use without flex or failure. It rides at the same height above the rail as standard mil-spec irons, so co-witnessing with your optic is straightforward. The sight uses the classic A2 aperture—the same proven design you'll find on countless service rifles—but with a key difference: it's designed to accept Trijicon replacement apertures if you want to refine your sight picture down the road.

At just 1.9 ounces, it won't bloat your rifle's weight budget. This is a fixed rear sight, so there's no dialing for distance; it's set and forget. Both rifle and carbine configurations are included, each offering 0.5- and 0.65-MOA adjustments respectively. Throw it on a flat-top, mount your optic forward, and you have a solid two-tier sighting system that doesn't rely on anything electronic to go bang when you need it.

Frequently Asked Questions

Will this rear sight co-witness with my scope or red dot?

Yes. The Combat Fixed Rear Sight mounts at standard mil-spec iron sight height, so it will sit lower than most optics and provide a clean co-witness on a flat-top receiver. If you want a 1/3 co-witness or lower third position, you'll need a riser or optic mount built for that height.

What's the difference between the rifle and carbine configurations?

Both configurations are included with your purchase. The carbine version offers 0.5-MOA adjustments, while the rifle version provides 0.65-MOA adjustments. Choose whichever matches your barrel length and intended zero distance.

Can I use a different aperture in this sight?

The Combat sight is designed to accept Trijicon replacement apertures, so you can swap in alternative apertures if you want a different sight picture or configuration down the line. The standard A2 aperture comes installed.

Is this sight compatible with my AR-15 flat-top?

This rear sight is designed for AR-15 platform rifles with a Picatinny rail on top of a flat-top receiver. It will not fit carry handle AR-15s or upper receivers with iron sights already built in.
