Magpul MBUS Rear Sight Gen 2, Black

The Magpul MBUS (Magpul Back-Up Sight) Gen 2 is a spring-loaded flip-up rear iron sight designed for use on Picatinny/M1913 rails. It serves as a reliable backup sight for AR-15 and compatible platforms when primary optics are unavailable or damaged.

Constructed with a durable polymer frame, this Gen 2 rear sight features tool-less windage adjustment ranging from 0.5 to 0.7 MOA per click, allowing for precise zeroing. The spring-loaded design allows rapid deployment when needed and folds down compactly when not in use.

Made in the USA by Magpul Industries, the MBUS Gen 2 maintains the rugged reliability the series is known for while remaining lightweight at just 0.1194 lb.
