Magpul MBUS Pro LR Adjustable Rear Sight - MAG527

A rear sight that thinks in ranges — the MBUS Pro LR adds calibrated, tool-less elevation to all-steel reliability.

The Magpul MBUS Pro LR Adjustable Rear Sight (MAG527) is the long-range thinker of the MBUS Pro family. Its elevation-adjustable aperture system is calibrated for extended distances, letting you dial for range with your fingers — no tools, no guesswork — while the dual apertures still cover fast close work and precise deliberate fire. If your irons are more than a formality, this is the rear sight that earns the rail space.

Construction is machined steel throughout with a corrosion-resistant finish. Folded, it keeps the trademark MBUS Pro low profile; deployed, it locks up solid, adjusts positively and holds its settings through recoil and rough handling.

Why shooters choose the MBUS Pro LR

• Calibrated elevation adjustment — dial for distance, tool-free
• Dual apertures — speed up close, precision at range
• Tool-less windage — full zeroing with your fingertips
• All-steel construction — settings that survive hard use
• Low-profile fold — clean under optics like every MBUS Pro
