Frequently Asked Questions
Will the Magpul MBUS Gen 2 Front Sight co-witness with a red dot or holographic sight?
Yes. The MBUS Gen 2 Front Sight is designed to co-witness with most red dot and holographic sights when mounted on a standard Picatinny rail at the appropriate height. For a traditional lower-third co-witness, pair it with a riser-mounted optic; for an absolute co-witness, use it with a lower, flush-mounted optic. Always verify your specific optic's height before purchase to confirm the correct sight picture.
Can I pair this front sight with a Magpul MBUS Gen 2 Rear Sight?
Absolutely. The MBUS Gen 2 Front Sight is specifically designed to be used alongside the Magpul MBUS Gen 2 Rear Sight, and the two are sold separately so you can mix and match with other compatible BUIS options as well. Together they create a complete, matched backup iron sight system optimized for the AR-15/M16 platform.
How do I adjust the elevation on the MBUS Gen 2 Front Sight?
Elevation is adjusted via the A2-style front sight post, which can be raised or lowered using a standard front sight adjustment tool or a cartridge rim. Rotating the post clockwise raises the point of impact, while counter-clockwise rotation lowers it. One full rotation equals approximately 1.25 MOA of adjustment at 100 yards on a standard AR-15 setup.
