Midwest Combat Back Up Rear Sight

The Midwest Industries Combat Back Up Rear Sight is a mil-spec height iron sight designed as a secondary aiming system for AR-platform rifles, M4 carbines, M16 variants, and other tactical firearms. This backup rear sight is essential for shooters running co-witnessed red dot or ACOG systems who require a mechanical fallback. It is also ideal for legacy AR builds, patrol carbines, and training platforms where backup iron sights remain policy or doctrine.

Constructed from durable materials, this backup rear sight protects a standard A2 rear sight aperture while offering the durability demanded in high-stress operational environments. The sight is designed to maintain zero integrity through repeated deployment cycles and training rotations. Its construction resists corrosion and impact damage, ensuring reliability in various conditions.

The mil-spec profile ensures compatibility with standard picatinny rail systems and does not interfere with common charging handle designs or forward-assist mechanisms. The A2 aperture geometry provides a familiar sight picture for operators, law enforcement, and uniformed personnel. This sight serves as a critical redundancy when primary optics are compromised or require battery rotation.
