Steel front sight for AR-15 - MAGPUL

The MBUS Pro. The all-steel backup solution that guarantees maximum functionality and durability with the smallest footprint at a price that is even smaller than the sighting size. Double opening, adjustable rear branch and tool-free, adjustable front height excel in all 1913 Picatinny Rail applications, including gas rail-height mounting blocks. It will not adjust with low profile or standard height gas blocks. Positive locking points keep the PRO MBUS front and rear at standard AR view height when deployed and so low when they are stowed that you will never notice them until they are needed. Front narrow width is compatible with most IR aiming lasers and light installations for the professional user.
