Primary Arms MD-20 SLx Gen II – Micro Red Dot Sight

The Primary Arms MD-20 SLx Gen II is a micro red dot sight built on a strong reputation of innovation, reliability and value. It undergoes rigorous field testing during the development stage to best serve the user in any environment. The red dot sight is the perfect blend of the advanced technology and features of the SLx MD-25 red dot and the form factor of the popular MD-ADS.  The newly designed body is aggressively styled and features low-profile, shielded adjustment turrets to minimize the risk of snagging in rifle cases or the bush.

The high power emitter provides true daylight brightness on the high settings yet retains both night vision compatibility and the 50,000 hour battery life you have come to expect. To further boost that battery life, the SLx MD-20 is equipped with AUTOLIVE motion activation. This feature turns off the optic when not in use and immediately comes back to life when it is moved, extending both the battery life and the life of the emitter. Compact, durable, and powerful, the SLx MD-20 is the perfect optic for your next build!
