Magpul MBUS Pro Rear Sight: Reliable Backup Sighting

The MBUS Pro (Magpul Back-Up Sight) represents the evolution of practical backup iron sights. This all-steel rear sight delivers maximum functionality and strength without unnecessary bulk, and at a price that reflects its straightforward design.

Construction and Durability

All-Steel Build: Case-hardened steel construction with Melonite QPQ finish provides extreme resistance to wear and corrosion. This sight will serve you reliably in harsh conditions and demanding use.

Picatinny Compatible: Mounts securely on any MIL-STD-1913 Picatinny rail, including rail-height gas blocks.

Operational Features

• Dual Aperture System: Small aperture (0.07 inches) for precision shooting; large aperture (0.19 inches) for rapid target acquisition
• Windage Adjustment: Low-profile knob requires no tools for quick adjustments
• Positive Detents: Locks firmly in both deployed and stowed positions
• Low Profile When Stowed: Sits so low when folded you'll forget it's there until needed
• Standard AR Sight Height: Deploys to proper AR-platform sight height for compatibility with your primary optics

Accuracy

Adjustment precision depends on your sight radius:

• 0.5 MOA per click with a 14.5-inch sight radius
• 0.4 MOA per click with a 20-inch sight radius

Made in the USA

This is a genuine American-made backup sight built to serve as your insurance policy when your primary optics fail or are unavailable.
