Magpul MBUS 3 Back-Up Rear Sight – Rapid-Select Aperture, Ambidextrous Deployment, Black

Compact precision. Fast target acquisition.
The Magpul MBUS 3 Back-Up Rear Sight delivers rugged reliability and rapid adjustment for AR-platform rifles and carbines. Featuring a Rapid-Select rear aperture system, this flip-up sight allows shooters to quickly switch between precision and close-quarters settings. Its ambidextrous push-button deployment ensures smooth activation from either side, even under stress.
Constructed from impact-resistant polymer with corrosion-resistant hardware, the MBUS 3 Rear Sight is lightweight yet built to withstand harsh conditions. Its low-profile design minimizes snagging when stowed, while compatibility with MIL-STD-1913 Picatinny rails ensures secure mounting on a variety of platforms. Whether used as a primary or backup sight, the MBUS 3 provides dependable performance when it matters most.

Key Features:

• Compatibility: Fits MIL-STD-1913 Picatinny rails on AR-platform rifles and carbines

• Aperture System: Rapid-Select rear apertures for versatile aiming options

• Deployment: Ambidextrous push-button flip-up mechanism for fast activation

• Construction: Impact-resistant polymer with corrosion-resistant hardware

• Profile: Low-profile, snag-resistant design for streamlined handling

• Color: Black for a sleek, tactical appearance

Why It Stands Out:

Magpul’s MBUS 3 Rear Sight offers upgraded features inspired by the MBUS Pro, combining rugged reliability with fast, flexible aiming. Its Rapid-Select aperture system and ambidextrous deployment make it an ideal choice for shooters who demand quick adaptability in any environment.

Perfect For:

AR-15 owners, tactical shooters, and enthusiasts needing a durable, flip-up rear sight with versatile aperture options.
