Based off of the AR-15/M16 front sight, the Magpul MBUS front flip-up sight is a durable, color injection molded, folding back-up sight. It conveniently folds down and locks into place but flips up with just a press of the button. The sight is adjustable for elevation and quickly mounts to any Mil-Spec 1913 picatinny rail.
The impact-resistant polymer construction provides lighter weight while absorbing shock, making this an incredibly durable sight. The spring-loaded sight is easily activated from both sides of the firearm so you can quickly engage a threat. The MBUS features protective wings to shield your apertures and further protect your sighting system.
Magpul was founded in 1999 with the intent of developing a simple device to aid in the manipulation of rifle magazines while reloading under stress. The company's name comes from this original product called the Magpul. Over the last 17 years, Magpul has continued to grow and develop using much the same mission and process with a focus on innovation, simplicity and efficiency.
Pair it up with our Magpul MBUS Rear Flip Up Sight (ARR-850).
NOTE: Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed forend on the same plane as the receiver rail.
