MBUS Pro — Product details

A corrosion‑resistant, all‑steel back‑up sight system that delivers professional strength and functionality with minimal bulk — at a price smaller than its footprint. Engineered for MIL‑STD‑1913 (Picatinny) rails (including rail‑height gas blocks), the MBUS Pro provides secure indexing, tool‑free adjustment, and a low installed height until needed.

Key features

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

• Dual‑aperture, windage‑adjustable rear with a low‑profile windage knob.

• No‑tool elevation adjustment via an elevation knob; positive detents on the knob for repeatable indexing.

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

• Narrow, rectangular front sight post selectable between two widths:

  • 0.04" Match — increased precision

  • 0.06" Standard — maximum visibility

• Low stowed profile — 0.432" height above rail at the tallest point when stowed and covers less than 1‑5/8" of rail.

• Standard AR sight height when deployed.

• Compatible with most IR aiming lasers and weapon lights thanks to the narrow front post.

• Fits most MIL‑STD‑1913 (Picatinny) rails, including rail‑height gas block installations.

Benefits

• Extremely durable and weather resistant for professional and hard‑use environments.

• Ultra‑low installed height minimizes interference with optics and accessories when stowed.

• Tool‑free, repeatable adjustments make field zeroing quick and reliable.

• Front post width options let the user prioritize precision or visibility.
