Our take: The MagPul Rear Back-Up sight is an amazing attachment to add to any AEG with a top RIS, Weaver, or Picatinny rail. This rear sight easily folds down to half of an inch on the rail, this is to eliminate any obstruction while looking through optics. With the push of a button the sight easily pops back up for use as an efficient iron sight. This Rear Back-Up sight is made of impact resistant polymer, able to withstand real-world abuse, and can be adjusted for windage and elevation. This Rear Sight creates a less cumbersome profile for any AEG and is easy to use, giving your AEG a sleek and fast look. MagPul truly does provide the "Unfair Advantage".
