Aim Sports MT201 AR-15 Low Profile Rear Flip Up Sight - Black Anodized

The Aim Sports MT201 is a low-profile flip-up rear sight purpose-built for the AR-15 platform. Machined from black anodized aircraft-grade aluminum, this rugged backup iron sight delivers dependable aiming whenever an optic is removed, fails, or simply is not part of the build.

The MT201 uses a dual-aperture design: a small aperture for long-range precision and a large aperture for quick close-range engagement. A ball bearing pivot detent keeps the sight solidly locked in the upright position once deployed, so it will not fold under recoil or rough handling. The low-profile housing measures just 2.5 inches long and folds flat against the rail when stowed, keeping the sight tucked out of the way under your primary optic.

Windage is calibrated at 0.49 MOA per click on A4-style rifle uppers and 0.65 MOA per click on M4 carbine uppers, giving you precise, platform-matched fine adjustment at the range. The MT201 clamps to any standard Picatinny rail, making it a straightforward drop-on upgrade or replacement rear sight for virtually any AR-15 upper.
