Midwest Industries Combat Rifle Sight Set

The Midwest Industries Combat Rifle Sight Set is the USA-made aluminum BUIS that splits the difference between polymer Magpul MBUS 3 and steel MBUS Pro. The front and rear sights are machined from 6061 aluminum with hard-coat anodizing, weigh roughly 3.2 oz for the full set, and lock into deployment with a positive detent. 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 is a single-aperture flip-up, 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 (spring-loaded) but consistent with how the steel MBUS Pro and KAC Micro behave. For shooters who want USA manufacturing, aluminum durability over polymer, 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.
