The Midwest Industries Combat Rifle Rear Fixed Sight (brand part no. MI-CBUIS) is a compatible, Standard A2-pattern rear sight built for AR-15, M4, and M16 platforms that need a durable, no-fuss backup or primary iron sight. Machined from billet 6061-T6 aluminum and finished in black hardcoat anodizing, it’s built to Mil-Spec height so it co-witnesses correctly with standard front sight posts. Windage adjustment runs 0.5 MOA per click on rifle-length systems and 0.65 MOA per click on carbine-length systems, giving precise zeroing regardless of your gas system configuration. The clamp torques to 35 in-lbs for a secure, no-shift mount, and it’s made in the USA.
