Midwest Industries MICBUIS Combat Rear Fixed Sight AR-15 Black

The Midwest Industries MICBUIS Combat Rifle Rear Fixed Sight delivers precision backup sighting capability for AR-15, M16, and M4 platforms. This hardcoat anodized aluminum sight provides reliable target acquisition when primary optics fail or require backup verification.

What Makes This Different

Unlike standard A2 rear sights, the MICBUIS features dual-aperture design with both close-quarters (.070") and precision (.040") peepholes. The sight mounts directly to Picatinny rails without tools and maintains zero through repeated installations. Hardcoat anodizing provides superior corrosion resistance compared to standard Type III finishes.

Key Features

• Dual-aperture design with .070" CQB and .040" precision peepholes
• Tool-free installation on standard Picatinny rail systems
• 6061-T6 aluminum construction with Type III hardcoat anodizing
• Same-plane height as standard A2 front sight posts
• Windage adjustment with positive click detents
• Low-profile design minimizes snag points
• Compatible with all AR-15, M16, and M4 variants

Field performance remains consistent across temperature extremes and high round counts. The sight maintains zero integrity through thousands of rounds while the hardcoat finish resists wear from tactical use. Law enforcement and military units rely on this sight configuration for backup sighting systems that function when primary optics experience battery failure or damage.
