SLx optics built their reputation for innovation, reliability, and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment. The Primary Arms SLx MD-20 Micro 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 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 new high-power emitter provides true **Daylight Bright** settings on the high end 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! #### **FEATURES** - **AUTOLIVE** Motion activation - 50,000-hour battery life - Low profile turrets - Ambidextrous top-mounted push button controls - Fits any industry standard micro mount and gives stated cowitness - Uses (1) CR2032 battery (included) - Ultra-sharp 2 MOA dot - Just 3.8 oz with battery - Fully multi-coated anti-reflective lenses - High-powered emitter for **Daylight Bright** illumination - Night vision compatible - Absence of parallax shift past 33 yards - Waterproof to 6ft. with turret caps on - Water-resistant with turret caps off - Fog resistant - Bikini lens cover included - Lifetime Warranty #### SPECIFICATIONS - Battery Life: 50000 Hours - Battery Type: CR2032 3V Lithium Coin - Brand: Primary Arms - Brightness: 12 Settings - Click Value: 1/2 MOA - Finish: Hardcoat Anodized - Material: Aluminum - 6061-T6 - Night Vision Compatible: Night Vision Compatible - Reticle: 2 MOA Dot - Reticle Color: Red - Size: Microdots - Warranty: Lifetime - Weight: 3.8 oz. ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
