Frequently Asked Questions
Will the MBUS Gen 2 Front Sight co-witness with my red dot or holographic optic?
Yes. The MBUS Gen 2 Front Sight is designed to co-witness with most standard red dot and holographic sights when mounted on an AR-15 or M16 with a full-height Picatinny rail. For lower-third co-witness setups, you may need a raised optic mount. Always verify your optic's mounting height and confirm sight alignment before heading to the range.
Is the MBUS Gen 2 compatible with the original Gen 1 MBUS rear sight?
While the Gen 2 front sight shares the same fundamental footprint and Picatinny rail interface as the Gen 1, Magpul recommends pairing the Gen 2 front sight with the Gen 2 rear sight for optimal aesthetic consistency and performance. That said, many shooters use mixed generations without functional issues, as the sight picture and elevation adjustments remain compatible.
How do I adjust the elevation on the MBUS Gen 2 Front Sight?
Elevation is adjusted using a standard AR-15 front sight tool or a small-tipped flat-head screwdriver inserted into the sight post. Rotating the post clockwise raises the point of impact, while counterclockwise lowers it. Each click provides a precise, incremental adjustment, and it is recommended to zero at your intended engagement distance on a stable shooting bench before field use.
