Midwest Industries Combat Rifle Sight Set

The Midwest Industries Combat Rifle Sight Set is the USA-made BUIS option that splits the difference between polymer Magpul MBUS 3 and all-steel MBUS Pro. The sight bodies use phosphate-finished steel with hard-coat 6061 aluminum bases, weigh roughly 2.6 oz for the full set, and lock into deployment with positive detents. Midwest Industries has been a fixture of the mid-tier AR parts market for two decades; their handguards, rail accessories, and sights all share the same matte black anodized look and consistent fit-and-finish.

The front sight uses an A2-style square post that's adjustable for elevation with a standard front sight tool. The rear sight uses an intermediate aperture, adjustable for windage via a tool-free knob. Sight radius and post width are matched to standard AR-15 carbine geometry — these were not designed for any specific platform variant, just standard MIL-STD-1913 rail mounting.

What the MI Combat Rifle Sights are not: spring-loaded. Deployment is manual; you flip them up with your finger or thumb. That's a small workflow difference vs the MBUS 3, but consistent with how the steel MBUS Pro and KAC Micro behave. For shooters who want USA manufacturing, more metal construction than polymer MBUS, and a lower entry price than the Pro, this set is the right answer. Midwest Industries also sells the Combat Rifle Sights in offset configurations (MI-CRS-OSS) and a fixed-offset variant (MI-CRS-FOSS-A2) for shooters who want both primary and offset BUIS from the same manufacturer.
