Introducing the Magpul MBUS® 3 Front Sight BLK, which offers the ultimate combination of functionality, durability, and value – creating a feature-rich back-up sight system. This front sight is designed with precision and ease of use in mind, allowing for quick and accurate targeting
Despite its lightweight construction, weighing only 0.09 lbs., it is impact-resistant and extremely durable, thanks to its polymer construction. The MBUS 3 Front Sight's design offers an aesthetically pleasing appearance.
The MBUS® 3 Front Sight is equipped with spring-loaded technology that allows for easy deployment using an ambidextrous push-button. It includes a dual width enhanced front post that offers tool-less elevation adjustment.
When stowed, the sight sits just 0.47’’ above the rail, ensuring a sleek and low-profile appearance. With its elevation adjustment, you can easily make precise adjustments to your aim. At a 14.5" sight radius, each click equals approximately 1 MOA (1.131”/100 m) while at 20" sight radius, it equals about 0.7 MOA (0.820”/100 m) per click.
Overall, the MBUS 3 Front Sight is the perfect choice for anyone looking for a reliable, compact, and durable back-up sight system that offers exceptional performance and value.
NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed forend on the same plane as the receiver rail. Because of this the sight is also not compatible with MOE Hand Guards.
