Exclusive to PrimaryArms.com and Primary Arms authorized dealers.

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.
   
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
  • 300 BLK 220 gr subsonic from 50 to 150 yards
  • .22LR 40 gr from 50 to 175 yards
  • 9mm carbine 115gr from 25 to 200 yards

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 reticle for this sight is a central 2 MOA dot, centered in a 65 MOA circle with four positioning points. The diameter of the circle reticle represents approximately 5'5" at 100 yards 170cm at 100m.

The HS503G is a proven micro dot sight with an auto-on function that switches on the power with a slight movement of the sight. It comes with a 1913 Picatinny base which is removable, revealing an Aimpoint Micro-compatible base underneath. It also comes with the lower 1/3rd co-witness riser mount shown in the photos.

Great but....

To start this sight is just what the doctor ordered if you have astigmatism or at least it's great for my level of astigmatism. I've had many different red dots of varying quality and this is the first one that the dot, in this case the chevron is sharp as can be and with the x3 vortex magnifier I was able to adjust it even sharper. The reason I removed one star is the front lens is a little out of position actually it's quite a bit out of position. I didn't notice it at first because I was so excited to test it out once I saw how great the image was that I missed it all together, it doesn't seem to effect performance but for something a little over $200 you expect a little better quality control. Will I buy it again? Hell yes! But I'm going to inspect it upon opening the package and I'll exchange it it I find the same problem.

ACSS in a red dot package. Best of both worlds!

I don’t know why I would ever buy another standard red dot!

ACSS reticle is very nice and more!

by -

Love how the reticle is laid out per caliber for your convenience. Running 5.56 and the accuracy is amazing at 400+ yards as well as under 100 yards! Once zero at 100 yds everything else is good too! Just follow the layout per your caliber and all is good. Need a bigger range to learn more.

Great value, bought a second one for another build.

Quality and features that are Unbeatable

by -

The Holosun quality and reputation, with PA secret sauce ACSS make this a RDS value that outshines competitors at near twice the price.
Rugged, feature-laden, quick acquisition, light enough, "idiot-proof" operation. Cop one *today*.

Love it

I’m fairly new at owning an AR-15 and after going through multiple optics on Amazon, from losing zero to my magnifier literally falling off while shooting, I’m glad I bought this sight. I love the ACSS CQB reticle, good for close range and for some distance. Getting this optic, you’ll get what you paid for and more. You’ll get dependability, and accuracy. You won’t be disappointed.
