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.

Ultralight, Great BDC, Uses Small Amount of Rail Space

by -

Has about the same mass as iron sights(140g for Holosun, 152g for my iron sights front and rear). I was worried that the BDC wouldn't be very usable without a magnifier due to many reviews online. I found this to be untrue. For precise shooting adjust the brightness down and the bleed goes away completely. While not the best for someone in a match environment(get a magnifier), for someone looking to put out some precise long range shots on targets the optic should be fine unmagnified. I will be pairing with a magnifier before hunting though; more for the magnification than a need for clearer BDC. I imagine a couple friends will be buying some after an upcoming range day.

Excellent inexpensive optic.

I’ve used this sight on an Ar15 as well as a Stoeger m3000. Performed great in the marsh bird hunting and it had not been gingerly moving around the boat. On the AR, the bullet drop is a bit cluttered at1x but when I put a 3x magnifier on it, that changed and made the reticle much better for my eyes. They are great options and extremely lightweight.

Primary Arms has became my favorite company

by -

I've own other Holosun scope and they haven't let me down so far. Holosun product is great as always. Only time will tell how durable it is.

Primary Arms service has been very fast. Order usually ship within one or two business days even during the pandemic. Unlike Optics Planet which take forever to ship and they don't give you the exact number of in-stock either. I will check with Primary Arms for firearms related stuff from now on. Recommended both company for a great product and great service.

Great product

Great optic, Exactly as described, Super Fast Shipping, Highly recommended company thank you Primer Arms

one of my favorite optics

by

The BDC works and can be seen without a magnifier. I recently added the holosun 3x magnifier (excellent) and it is even better for shooting at distance. Auto on feature means it always ready to go. this is one of my favorite optics. I will be purchasing another in the future.

ACSS RETICLE ROCKS

by

Bought this reticle and mounted to my 10.5 inch AR pistol. The reticle itself without a 3x multiplier is ok. But ad a multiplier and this thing rocks. Much more accurate than a standard red dot. Adjusted for auto brightness and I am G2G.

Love these optics

by -

I have 2 of these HS503G's. One on a 5.56 16" and one on a 300BO 10.5". I absolutely love them. I have owned the one on the 300BO for 5 years and just replaced the battery early this year for the first time. Battery life is outstanding. I use both of these in conjunction with a Vortex Micro 3x magnifier with the QD mount and I can just switch it between platforms when in use. AWESOME setup!

Awesome Red Dot / Reticle

by -

This is my 2nd HS503G: one on a CZ Scorpion for around 3 years and this one on a 300BO AR Pistol. Very happy with durability and i really like the ACSS CQB reticle. Easy to zero and very functional. One note: keep extra batteries on hand if using as a ‘truck’ gun; the vibration will drain them quickly.

Very nice dot for the price.

by -

I’ve got about 200 rounds on this so far and I must say I’m quite impressed. Haven’t had the opportunity to push it past 100 yards but it’s doing well at that range.

Reticle holds true on high mounted 9mm 5.5" PCC

by -

THIS is what a modern red dot should be! Rings steel at 200 yards on a 5.5" PCC! Definitely extends the effective range of the weapon compared to any other reflex sight out there. Eotech, aimpoint and trijicon should take some notes.
