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.

Very Impressed

by -

I've been skeptical of red dots for quite some time, due in part to my astigmatism that makes most red dots into a blurry smear. The ACSS reticle works with my eyes, maybe because it's more than just a single concentrated dot.

At 1x, the big circle and center chevron work very well for distances out to about 100 yards. I like having the fine aiming point of the chevron for precise shots (at least as precise as 1x will give me.)

The BDC dots are pretty much useless for me at 1x, but the reticle really shines with a 3x magnifier. (I'm using the PA LER magnifier.) With the dot and magnifier, hits at 300 yards on 2/3 IPSC steel targets are very doable with 300BO.

I liked this setup so much that I've purchased three of them. They also work great on 10/22. Those with better eyes might be able to use the bullet drop dots for shotgun slugs.

I like the side-mounted battery better than the tray. I wish it had the solar panel, but I think this optic is well worth the money even without it.

Premium product with a budget price, it’s a no brainer.

Astigmatism

by

I've had many red dots over the years and because I have astigmatism they've always been a bit distorted some more than others including some other Holosun's that I've owned so it was always a case of picking a spot on the dot which in some cases was a smear and on others a starburst and going with it, not true with this sight. After years of dealing with it I started looking around for articles and videos dealing with astigmatism and optics and I found a few good ones and they gave this as one option, the hs510c being another but since it's going on an AR pistol I chose this and I was not disappointed! I've never seen a more crisp reticle on a red dot sight! If you suffer from astigmatism this will not disappoint! And as always primary arms delivery was prompt! Thank you!

Love it!

Holosun ACSS Reticle

by -

Great red dot. Mounted on my 7.62x39 upper. Holds zero just fine. I found the ACSS reticle difficult to see clearly with my old eyes. But when coupled with the PA 3x magnifier, the ACSS reticle is a game changer for reaching out to distance. This has quickly become my favorite red dot. After roughly 300 rounds I ordered a second one for my .223 wylde upper. I would recommend.

Best Red Dot for the Price

by -

Love the ACSS Reticle. Very accurate once dialed in.

Chevron is under estimated

by -

Anyone who likes red dots and hologram sights will find this setup to be the best of both worlds.

Once you go chevron
Nothing else matters mohn!

Best reticle for a red dot imo!

Purchased this for a 11.5 carbine, I’ve always been a fan of Primary Arms reticles and Holosuns reliability and customer service. You get the best of both worlds in this optic.
