Primary Arms SLX-MD-20 Advanced Push Button Micro Red Dot Gen II Product Details

Get affordable precision in a tough-as-nails package for your custom gun with the Primary Arms SLx MD-20 Gen II micro red dot sight. Built to go head-to-head with larger, “name brand” competitors, the SLx line of performance optics strikes the right balance between power and price, refusing to compromise on either. Packed with features, engineered for precision, and designed with the needs of real-world tactical situations in mind, the MD-20 gives your long gun faster target acquisition and improved accuracy downrange. 

Better Price and Precision

The Primary Arms MD-20 Gen II red dot sight is an excellent choice for the range, your personal defense weapon, or on a duty weapon you depend on while you serve and protect. Packed with premium features, it’s ready to help you put round after round down range and right on target.

  • Protected by a hard anodized aluminum housing for lightweight durability that’s ready for whatever the field throws at it.
  • Get up to 50,000 hours of service life from a single CR 2032 battery that can be easily changed without removing the optics from your weapon or re-zeroing the sight.
  • Choose from fourteen brightness settings using the convenient, ambidextrous top-mounted buttons—12 daylight settings and two-night vision compatible options.
  • The entire unit weighs less than 4 ounces with the battery in place.
  • Bright red 2 MOA center dot for intuitive precision aiming.
  • Includes a low-profile 1913 MIL-STD Picatinny rail mount that drops your eye to the same level as the top of the receiver rail. Risers are available for weapons with a stock that raises to receiver rail height.
  • AutoLive motion-activated illumination saves your battery life when the weapon is still and not in use.
  • The parallax-free lens offers unlimited eye relief.
  • Covered by the Primary Arms Limited Lifetime Warranty.
