Holosun Paralow HS503G Red Dot Sight - ACSS Reticle
Primary Arms and Holosun have combined forces to bring you the power of the patent pending ACSS® CQB reticle in a red dot sight for the first time! The problem with dot sights is that a large dot is great up close but less useful at distances beyond 100 yards, because the dot becomes too large to aim with precision. A small dot used in conjunction with a magnifier fixes that problem, but is slower to acquire in close range snap shooting. The ACSS reticle uses a large chevron that the eye picks up very easily for up close shooting. At longer distances, the tip of the chevron is an infinitely small aiming point perfect for taking precise shots. 

The ACSS features three BDC dots underneath the chevron, allowing an unprecedented 600 yards of bullet drop compensation in 7.62 NATO or 5.56 NATO calibers. 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. 

The HS503G is a proven micro dot sight with 50,000 hours of battery life at a medium setting. It comes with a 1913 Picatinny base (low height and raised one) which is removable, revealing an Aimpoint Micro-compatible base underneath. It also comes with the absolute co-witness riser mount shown in the photos. 

Features: Primary Arms Exclusive! This is the only place to get Bullet Drop Compensation to 600 yards, wind holds and auto ranging all in a night vision compatible micro red dot with 50,000 hours of battery life! 

Using "zero" ranges of 25, 50, or 100 yards, the ACSS BDC is compatible with the following calibers:
  • 5.56 NATO / 5.45x39 from 100 to 600 yards
  • 300 BLK / 7.62x39 from 50 to 450 yards
  • 12 gauge 1 oz. slug from 25 to 150 yards
  • 7.62x54R from 100 to 600 yards
  • 7.62 NATO / .308 Win from 100 to 600 yards

  • 9mm carbine 115gr from 25 to 200 yards  
Please note that the front, or objective lens is installed at a precise angle in order to reflect the red dot back to the user’s eye. This angled objective lens is common to all reflex‐style optics.
