Midwest Industries MICRSR Combat Rifle Rear Flip Sight Black for AR-15/M16/M4

The Midwest Industries MICRSR Combat Rifle Rear Flip Sight is a low-profile, flip-up rear iron sight purpose-built for the AR-15, M16, and M4 platforms. Designed for shooters who co-witness a primary optic or need a reliable, snag-free back-up sighting solution, this rear sight deploys on demand and lays flat when not in use.

Construction pairs a hard-coated 6061 aluminum base with an alloy steel sight body in a Black finish. The base clamps directly to a Mil-Spec 1913 Picatinny rail, and dual locking detent springs give the aperture a crisp, positive lock-up in both folded and deployed positions. When folded, the sight sits at a super-low 0.388" centerline to keep it out of the way of optics and accessories; when flipped up, it returns to standard Mil-Spec sight height so it co-witnesses cleanly with a standard A2 front sight post.

Adjustment is tooled for the field, with a 0.5 MOA per-click windage knob that lets the shooter dial corrections quickly and accurately. The dual-aperture design includes an intermediate setting for fast close-range work and a fine aperture for longer-range precision. Overall length is approximately 4.6" with an installed weight of just 1.6 oz, so the sight adds minimal bulk to the rifle's rail.

Whether you're running a flat-top AR-15 carbine and need a rugged back-up to your red dot, or you want a dependable iron sighting solution for a defensive or duty rifle, the Midwest Industries Combat Rifle Rear Flip Sight delivers the strength, precision, and snag-free profile the company's rails, mounts, and handguards are known for.
