CAA Gear Up offers a complete line of backup iron sights (BUIS), flip-up sighting systems, and compact red dot optics specifically designed to mount to the top Picatinny rails of Micro Conversion Kit (MCK) and Micro Roni platforms. Designed for rapid target acquisition, zero holding reliability, and seamless co-witness capabilities, these targeting solutions allow shooters to maximize accuracy across close-quarters and extended range scenarios.

| Aluminum Flip-Up Sights (MCKBUS-AL) | $65.00 – $75.00 | Aircraft-grade 6061-T6 aluminum; spring-assisted push button. | Heavy-duty recoil rating; ultra-low profile folded stance; precision click adjustments. |
| MCK 1x20mm Red Dot Sight | $79.99 – $99.99 | Anodized aluminum housing; 2 MOA red dot reticle. | 1x magnification; 11 brightness settings; multi-coated lens; includes Picatinny riser mount. |
| Fixed Polymer Iron Sight Set | $29.99 | High-impact polymer; fixed low-profile stance. | Universal Picatinny fitment; lightweight emergency alignment sights. |
Spring-Loaded Deployment: Push-button mechanism instantly snaps sights up into ready position when main optics fail or are detached.
Dual Aperture Rear: Features both a wide aperture for fast close-quarters target indexing and a small aperture for long-range precision.
Universal Fit: Mounts to any standard MIL-STD-1913 Picatinny rail section across Gen 1, Gen 2, Gen 3, and EVO chassis.
Rugged Construction: Machined from 6061-T6 aircraft aluminum with a matte black hard-coat anodized finish for maximum durability under hard use.
Tactile Adjustments: Precision click-wheel windage (rear) and elevation (front) adjustments that stay locked under sustained recoil fire.
Fast Acquisition: 2 MOA red dot reticle provides rapid eye alignment without limiting field of view or eye relief.
Co-Witness Compatibility: Pairs with MCK polymer or aluminum flip-up sights to achieve an absolute or lower 1/3 co-witness sight picture when mounted on the top chassis rail.
💡 PRO TIP: When installing optics and flip-up sights on your MCK, place the rear flip-up sight on the rearmost Picatinny slot and the front sight as far forward on the top rail as possible to maximize your sight radius and operational precision!
