SLx optics have built a 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-25 Gen 2 Microdot with ACSS CQB reticle now comes with AutoLive improving the functionality of an already amazing red dot sight. With this red dot sight the moment you pick up your rifle the dot will turn on and be ready precisely when you need it. After sitting motionless for a brief period of time the red dot will shut off and conserve battery. Still featuring the same lightweight and durable design with a field of view that rivals larger 30mm red dots the MD-25 Gen 2 is a no-brainer upgrade to add to your collection. The ACSS CQB reticle features three BDC dots underneath the chevron allowing an unprecedented 600 yards of bullet drop compensation for 7.62 NATO or 5.56 NATO calibers in a compact red dot sight. Auto ranging and wind leads are also incorporated into this smart reticle. A CQB horseshoe grabs the eye instantly for close quarters shooting and also approximates the spread pattern of 00 buckshot at 25 yards.
