The familiar true 1x magnification and high precision Steiner optics ensure a razor-sharp image - ideal for both-eyes-open shooting and full situational awareness. The 8 brightness settings - 6 for daylight, 2 for night vision - have been retained, as has the convenient auto-off function. A new, enlarged switch improves handling, especially when wearing gloves. And thank to its proven footprint, the MPS remains compatible with nearly all optics-ready pistols and mounting plates on the market. The reinforced all-metal housing with a deep-set viewing window and a durable metal hood makes the MPS one of the most rugged red dots sights on the market - built for maximum reliability in extreme conditions.
