Who This Is For
The Magpul MBUS Gen 2 Front Sight is ideal for AR-15 owners who want a dependable, low-profile backup sighting solution — whether you're running a primary optic and need a co-witness failsafe, building a lightweight patrol rifle, or simply upgrading from worn-out factory sights.

Frequently Asked Questions
Will the Magpul MBUS Gen 2 Front Sight co-witness with my red dot optic?
Yes — the MBUS Gen 2 Front Sight is designed to co-witness with most popular red dot optics when mounted on a standard flat-top AR-15 upper receiver. For absolute co-witness, you'll want your optic mounted at the appropriate height; lower-third co-witness is also achievable depending on your optic's mount height. Pair it with the MBUS Gen 2 Rear Sight for a matched backup system.
How is the elevation adjusted on the MBUS Gen 2 Front Sight?
Elevation is adjusted using a standard AR-15 front sight adjustment tool or a bullet tip inserted into the detented sight post. Rotating the post clockwise raises the point of impact, while counterclockwise lowers it — the same familiar method used with mil-spec A2 front sight posts. No gunsmithing is required.
Is the MBUS Gen 2 as durable as metal backup sights?
While the MBUS Gen 2 is constructed from high-quality color-injected polymer rather than steel or aluminum, it is purpose-built to handle the rigors of field use. The protective wings around the sight post guard against accidental damage, and the detent-and-spring retention system keeps the sight securely locked in both the deployed and folded positions. For most civilian and law enforcement applications, the Gen 2's polymer construction offers an excellent balance of durability and weight savings.
