Leupold built the Mark AR MOD 1 3-9x40 Riflescope
for short-to-medium-range shooting and outfitted it with a P5 BDC
elevation dial for a .223/5.56, 55-grain FMJ projectile with a muzzle
velocity of 3100 feet per second. The optical system features 3-9x zoom,
Mulitcoat 4 anti-reflection coatings that reduce glare and increase
transmission, and a linear field of view range of 33.5-14.1' at 100
yards. To help you compensate for wind drift and ballistic bullet drop,
the scope offers a 60 MOA windage and elevation adjustment range with a
1/10 MIL impact point correction.
The Duplex Reticle is defined
by heavy posts and a thin crosshair that are visible well on any
background or in twilight. Because of its location in the second focal
plane, the reticle will remain the same in size as you change zoom
The aluminum housing is lightweight, durable,
waterproof, and argon-krypton-filled fogproof. It is compatible with 1"
riflescope mounting rings and has a lockable fast focus eyepiece with a
low-profile tactile zoom lever, which helps you with an instant
one-finger zoom adjustment.
