Magpul Front and Rear Flip-Up Sights



Get some of the best and lightest backup sights out there.  Get these MBUS from Magpul. These sights offer standard sight height for cowitnessing purposes.  They're super lightweight yet durable, because they're made from polymer, not metal.  They deploy and stow fast too.  Just push down one of the tabs on either side, and they flip up lightning fast.  Done with 'em?  Fold 'em back down, and they lock in place.  Simple.  This Magpul set of MBUS can do everything backup irons can do, but they're easier to use, more convenient, and they stay out of your way when not in use.  Grab a set and see for yourself.
