Product Information

The Mark AR® MOD 1 is proof you don’t need to spend a fortune to turn a basic AR into a badass. We designed this series to squeeze every last bit of performance possible from your AR, MSR, or bolt-action rifle, so you can be on the front line of performance.


  • 2nd Generation Argon/Krypton Waterproofing
  • Dual Use
  • MARK AR® MOD 1 P5 Dial
  • Multicoat 4
  • One inch Maintube

Features our exclusive, proprietary Argon/Krypton gas blend, which nearly eliminates the effects of thermal shock, and reduces the diffusion of gases sealed inside your scope even more than our proven nitrogen technology already does.

All Leupold® optics offer performance that makes them equally at home in hunting or tactical environments, thanks to their outstanding accuracy, legendary ruggedness, and absolute waterproof integrity. 

All Mark AR MOD 1 riflescopes feature 0.1 mil P5 dials with an elevation BDC dial for a .223/5.56, 55gr FMJ projectile with a muzzle velocity of 3100 FPS..

The Multicoat 4® lens system delivers extreme clarity from edge to edge of the visual field, outstanding contrast, and a bright sight picture even in extreme low-light conditions.

Durable and compact, the one-inch maintube is lightweight and fits more legacy rings.
