The Magpul MAG527-BLK MAG527 has been recently upgraded to become the Mbus Pro LR. It retains the signature slim profile and elegant design of the original Mbus Pro, enhanced with a new elevation adjustment wheel. This feature allows for precise engagement with targets over fluctuating distances. Constructed entirely from high-quality steel, it offers a robust sight solution without the need for tools in the adjustment process. This system combines maximum strength, outstanding corrosion resistance, and practical utility in a sleek, compact form. Beneficial positive detents ensure that the Mbus Pro LR retains the standard AR sight height when deployed. When stowed, the sight becomes virtually invisible, thanks to its extremely low-profile design.
