Magpul - MBUS® 3 Sight – Front, Various Colors

MBUS Value Meets MBUS Pro Features.

The MBUS 3 Front Sight is the next evolution in the Magpul Back-Up Sight (MBUS) line, combining the strengths, features, and value of both the original MBUS and MBUS Pro Sights. This feature-packed sight is significantly reduced in size compared to the original MBUS, sitting at just 0.47” high when folded and weighing only 25 grams with hardware.

Constructed from Magpul’s impact-resistant polymer, the MBUS 3 Front Sight offers durability and light weight, with aesthetics derived from the MBUS Pro. The sight uses spring-loaded technology for quick deployment with an ambidextrous push-button. It deploys at standard AR-height and includes tool-less elevation adjustment of a dual-width enhanced front post, similar to the MBUS Pro model.

Available in Black, Flat Dark Earth, and OD Green, the MBUS 3 Front Sight offers versatility and ruggedness for your AR platform.
