MBUS Pro — Product Details

A corrosion‑resistant, all‑steel back‑up sight system that delivers maximum strength and functionality with minimal bulk — and at a price smaller than its footprint. The MBUS Pro is engineered for professional use on MIL‑STD‑1913 (Picatinny) rails, including low‑profile rail‑height gas blocks.

Overview

• All‑steel construction finished with QPQ salt‑bath nitride for extreme wear and corrosion resistance.

• Compact, rugged design: positive detents ensure solid lockup in both stowed and deployed positions.

• Low installed height when stowed, yet standard AR sight height when deployed — ideal for co‑witness and low‑profile setups.

• Narrow front sight profile compatible with most IR aiming lasers and weapon lights.

Key Features

• Dual‑aperture, windage‑adjustable Rear Sight with a low‑profile adjustment knob.

• No‑tool, elevation‑adjustable Front Sight for fast zeroing without tools.

• Positive detents in both the up and down positions for reliable indexing.

• Fits most 1913 Picatinny rails, including rail‑height gas block installations.

• No tools required for normal adjustments and operation.

Benefits

• Built to survive harsh conditions while maintaining precision adjustments.

• Extremely low profile when stowed—won’t interfere with optics or accessories until needed.

• Professional‑grade compatibility with IR aiming devices and lights thanks to the narrow front post.

• Easy to use in the field: quick deployment, secure lockup, and tool‑free adjustment.
