Magpul has updated their low cost Magpul Back Up Sights. Designed to fit a MilStd 1913 (Picatinny) rail, the MBUS II comes as two separate components; a rear and a front sight. Both fold down out of the way and flip up into place. The new versions are both slightly more streamlined than the earlier sights and they have improved the locking mechanism for the front sight post. For the rear sight they have developed the new N.A.W.S. (No Aperture Window Sight) option. It works when you fold down both apertures and frame the target within the protective wings for snap-shots in Close Quarters Battle situations.
My BHI-15 came with the previous version and it is a good choice but I am glad to see they have worked on the front sight post. Just make sure that you actually take your rifle out and zero the MBUS. It is an M16-style sight and has to be zeroed. Also, make sure you practice with it. While it will most likely be your emergency sighting system, it won’t do any good if you can’t use it.
Magpul has also been so kind as to provide a couple of notes on use: “Cannot be mounted to a railed gas block due to excess heat issues. Front MBUS must be mounted to a railed fore end on the same plane as the receiver rail. Because of this the sight is not compatible with the MOE Hand Guard.”
