Magpul recently announced their new MBUS Pro, an all steel construction sight for the AR-15. Their extremely popular MBUS polymer sights were the go-to budget sights for quite some time because of their low price and high build quality. The rear MBUS Pro sight has both large and small same-plane apertures and is just .375″ tall them folded down. The front MBUS Pro sight is slightly thicker at .432″ tall when stowed but doesn’t require any tools to adjust elevation, a pretty darn cool feature if you ask me. Both sights are expected to be available by late summer 2013. You an find info on the new MBUS Pro over at Magpul.com.
