The SLx optic line are a step up from the basic red dots that made Primary Arms a household name. Yes, Charlie's likes to bring your the best of the best, and we have been imprressed with how PA balances quality with price. You can think of this as part of our "value" line, but we have not found a bad Primary Arms sight, and certainly saving a few dollars is important on some builds.
The Primary Arms SLx MD-20 Micro Red Dot Sight is the perfect blend of the advanced technology and features of PA SLx MD-25 red dot and the form factor of our wildly 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!
