What is the difference between Magpul MBUS Gen 2 and MBUS Pro?

MBUS Gen 2 sights are made from polymer and are lightweight, while MBUS Pro sights are made from steel and offer a lower profile and greater durability.

Are Magpul MBUS sights compatible with all AR-15 platforms?

Yes, MBUS sights mount to any MIL-STD-1913 Picatinny rail and are compatible with most AR-15 upper receivers and handguards.

Do MBUS Pro Offset sights co-witness with red dots?

No, offset sights are mounted at a 45-degree angle and are designed to be used as a backup to a primary optic, not for co-witnessing.

What is the newest Magpul MBUS model?

The newest model is the MBUS Gen 3, which offers an even lower profile than Gen 2 and improved sight post geometry while retaining its polymer construction.
