Description

If you’ve ever been shooting your long gun and your optic has gone down, then you can understand the absolute necessity of having BUIS, or backup iron sights.  Whether your front sight is fixed, like the A2-style of the M4, or you have a fixed sight mounted on your pic rail, this Magpul Rear Flip-Up Sight is the perfect compliment.

To use it, just push down one of the tabs that are extended on either side, and it pops up super fast.  To stow it, simply push it back down , and it locks in place out of the way of any other optic you may have mounted on top.  As far as cowitnessing goes, it lines up perfect in line with an AR-15 / M4 / M-16 sight height.  And for those of you trying to shave those precious ounces off the weight of your rifle, relax; this thing is polymer.

Magpul Rear Flip-Up Sight Features:

• Protective Wings Shield the Dual
• Reduced Size
• Heavy Duty Impact Resistant Polymer Construction
• Spring-Loaded Flip Up
• .51” Above Rail System
• Lightweight Backup Sights

MagPul continues their tradition of innovation and cost efficient products with this MagPul AR-15 Rear Flip-Up Sights. This MBUS (MagPul Back-Up Sight) fits standard Picatinny Rail Systems, by way of clamping onto the rail system. Once attached, the Rear Sight sits about .51” above the rail, making it easy to see around and not obtrusive to the operator’s line of sight. Coming spring loaded, this sight is incredibly durable and resistant to wear and tear. MagPul added a feature to ensure folding of the sight under impact. Along with allowing for the rear sight to have the ability to be folded with either small or large aperture in position. Easily adjusted for height, this sight is a great, easy, and cheap addition to any AR-15 or M16 platform. Compared to a typical metal back up sight, this polymer sight aids in a lighter weight design along with durability that is comparable if not superior to that of the metal. Not to mention the comparative cost! This polymer back-up sight is a no brainer for every operator.
