The Magpul MBUS Pro Front Sight is a durable Flip-up Back-Up Iron Sight (BUIS) that is extremely durable and has easy, hand-adjustable elevation setting.  The integrated Picatinny mount makes it easy to mount this high quality sight to any rifle.



The Magpul MBUS Pro front sight is made from steel.  The steel used for this sight is case hardened for increase strength and durability. A Melonite QPQ finishing technique is used to promote even greater resistance to wear & corrosion.  The low profile size an minimum bulk of this sight protect it from becoming accidently snagged.



Unlike other back-up iron sights on the market, the MBUS Pro front sight does not require the use of tools to make front sight elevation adjustments.  The front sight has an integrated adjustment wheel that can be easily manipulated with your finger to make elevation adjustments.


Low Profile

When not in use, these sights easily fold away and become a light and compact package with minimum bulk.  With this front installed on your rifle, it will only add an additional 1.5 ounces.  When in the folded down position, the maximum height of the sight is only ~0.43” above the rail.  This low profile will insure that the sight does not interfere with your primary optic.  When deployed, the front sight will stand erect at the standard AR-15 sight height.  The sight is help firmly in place by a positive locking detent.  The detent is strong enough to maintain the upright position of the sight even during heavy recoil.



The Magpul front sight has an integrated mounting platform.  The mounting platform is compatible with any MIL-STD 1913 Picatinny style rail.  Due to it’s steel construction, this sight is capable of being mounted onto a receiver height gas block.
