The MBUS (Magpul Back-Up Sight) is a low-cost, color injection molded, folding back-up sight.

Preferred BUS
I've used this and other flip-up BUS's and the Magpul is my choice for it's price point and overall quality. All metal flip-ups might be superior to the Magpul depending on mission requirements. But for everyday, civilian use, you can't go wrong with Magpul sights.
