The MBUS 3 Front Sight is a compact, spring-loaded back-up sight that delivers the durability and lightweight performance of the original MBUS in an even smaller polymer package. Designed to take up minimal space on your rifle, it attaches to most M1913 Picatinny-railed forends and maintains standard AR sight height when deployed for broad compatibility.

Features

When stowed, the MBUS 3 Front Sight sits at just 0.47" tall and 1.38" wide, reducing snag hazards and keeping your backup sight out of the way until needed. The spring-loaded design with an ambidextrous push-button allows fast and positive deployment on demand.

The sight includes two selectable front-post widths in one unit: a 0.06" Standard width for maximum visibility and a 0.04” Match width for increased precision in more demanding shooting scenarios.

NOTE: The MBUS 3 Front cannot be mounted to a railed gas block due to excess heat. It must be installed on a railed forend on the same plane as the receiver rail. Because of this, it is not compatible with Magpul Hand Guards.
