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.

Fantastic Product. Fun to Shoot With.

I'll keep it short. Great product. Put it along side a Primary Arms 3x magnifier and I couldn't be happier. Easy to use and accurate. Haven't had any issues with it.

16" 308 barrel

I mounted this red dot on a DPMS Gen 2 Recon. I zeroed as instructed, 1 inch high @ 100 yards for a 308. I ran a biathlon with this set up and it came through like a champ! 300, 400, 500 yard shots were a breeze using the appropriate dots. The chevron handled everything closer. I absolutely love this red dot!

OUTSTANDING!!!

Was a little wary after other red dot experiences. After a couple of range days this red dot is my new best friend. Plenty of adjustment for bright or dim days. BDC is absolutely dead on at extended ranges. I will be buying a couple more of these without a doubt. Great to see a product that delivers as advertised. Great job Holosun and Primary Arms!!!!

Looks good so far!

After some research on red dots and the like I bought two of these when they came in stock. Unlike many people I'm not using an AR at least one is going on an FAL. The higher mount will allow use of irons underneath fairly well if its mounted close to the rear sight. I liked the lower mount as its closer to bore axis. The reticle looked too small at first but once I mounted it on a rifle it was much better. I have not zeroed it yet so it still remains to be proven with repeated 308 recoil. I'm an iron sight rifleman but at some point our eyes stop working as easy and this sight seems to be just the ticket: a fine illuminated aiming point with calibrated aiming points for the distances I can actually SEE. The motion activation Is a good feature. I do have to admit I distrust electronics and technologically advanced gear as I expect it to fail when truly needed. But i'll give this sight a good evaluation and see how it does.

Great product and great customer service by Primary Arms as usual!

Received this red dot earlier this week and took it out to the range today. After shooting about 300 rounds I can say that I like this sight a lot. The ACSS reticle and the glass itself are crisp and clear. For the money spent I am definitely pleased. Beyond that I received it within 3 days of placing my order. A+ for PA!

Get it.

Was having a lot of trouble deciding whether I wanted this or the 1-6x. I love how quick a red dot is. I wanted the distance of a scope. While a scope is better served trading long shots this particular red dot with a magnifier is actually a worthy competitor. That would be a ridiculous thing to say with any other red dot. This one will obviously not be as ideal when taking a long shot but imagine having the reasonable ability to do so but then have ask the advantages and more of a red dot. The reticle is freaking sweet. With the circle dot it is very fast acquisition close range. At long ranges the chevron is awesome at finding that pin point you want to shoot to. Next thing. On a second focal plane scope the reticle is only really accurate on its last setting. So all the other power settings you have to toggle through to get to it are fine and all...but personally I'd rather just slap my magnifier over this red dot and be there immediately. I have the primary arms 3x ler. I plan on getting the 6x on a quick detach just for kicks. I'm loving the red dot. Get whatever you want...the 1-6x is still in my future but for now I got third and am glad I did. Get one of the two...heck get both. No regrets.

Woah

by

unbelievable for that price. got to test it out at the range today and it works flawlessly. i had ordered the hs403b and returned it because the dot was not sharp and it was distracting and the battery tray was sub par. this fixed all of those. reticle is tack sharp even in bright daylight with brightness all the way up. battery know is on the side under a screw cap and build is very robust for the price. other than reliability of the name it makes me wonder why other sights are so much more expensive.

Good to go

by

In my honest opinion which isn't an expert one for the price you can't beat this little red dot. It's packed with features and does its job what more can you ask for. Consistently hitting a 6 inch paper at 100 yards with my Tavorx95. Its also built very solid in my opinion it doesn't feel or look cheaply made like a lot of others in this value price range. I'm probably ordering another Holosun dot here in the near future and the customer service at Primary Arms is top notch.

Mount broke after two shots

by -

So far the site works great. Fit and finish on par with my T1 and T2. The red dots crispness is as good if not better than the T2 (which is improved over the T1) and much better than the eotech that this sight is replacing. If it proves to be as durable as the aimpoint then it will be a great sight for years to come.
Now the one big negative ......the mount. It looks great, fits great, but broke after two shots on a 300BLkout. Took two sight in shots, then reached up to remove the elevation cap and the sight fell off the gun into my hand. The screw broke off half way thru the threads in the base of the mount. I used and FAT wrench to torque it to about 20-25in/lbs and used blu 242 thread locker on install. SO needless to say I am extremely disappointed in the mount. Do yourself a favor and order a LaRue, Midwest or American Defense mount when you order this sight and you won't waste a trip to the range.
5 stars for the red dot and 1 star for the mount.
