【All-Steel Construction. QPQ Nitride Finish. Tool-less Windage Adjustment. Dual Apertures. 0.38" Stowed Height.】

The Magpul MBUS Pro® Rear Sight is the gold standard for back-up iron sights (BUIS). Built for those who demand absolute reliability when their primary optics fail, the MBUS Pro combines a sleek, snag-free profile with the uncompromising durability of solid steel. Engineered to withstand hard use while maintaining a precise zero, it is the essential upgrade for any tactical or competition rifle.

Key Features & Tactical Benefits:

• 🛡️ Battle-Ready Durability: Constructed from solid steel and finished with a QPQ salt bath nitride process. This extreme hardening treatment provides maximum resistance to wear and corrosion, ensuring the sight performs in any climate.
• ⚙️ Tool-less Windage Adjustment: Flexibility is key in the field. The integrated windage knob allows for on-the-fly adjustments without the need for specialized tools, getting you back on target faster in changing situations.
• 🎯 Versatile Dual Apertures: Features a secure flip-up/down aperture window. Choose the narrow aperture for precision long-range engagements or the wide aperture for enhanced field of view in close-quarters and low-light scenarios.
• 📐 Ultra-Low Profile Profile: When stowed, the sight sits only 0.38” above the rail, staying completely out of the way of your primary optics and minimizing snag hazards. When deployed, it sits at standard AR sight height (1.41” above rail).
• 🔒 Rock-Solid Zero Retention: Positive detents keep the sight, windage knob, and apertures securely in place during high-round-count sessions and aggressive handling.
