The MBUS Gen 2 improved on the original MBUS with a refined spring-loaded deployment mechanism and a more compact folded profile. The front sight deploys to the vertical position and pairs with a compatible MBUS Gen 2 rear sight to form a complete polymer BUIS set, ensuring the firearm remains usable for iron sight shooting if the primary optic fails. Position the front sight at the forward end of the top rail for the correct sight radius with the paired rear sight. The MBUS Gen 2 front mounts to any standard Picatinny (MIL-STD-1913) rail on an AR-15 flat-top upper receiver and is a direct drop-in installation requiring no modification to the host firearm.
