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.
