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.

8 Year Review

-Pros: Maintains zero. Great reticle; able to get hits on steel out to 400 yards consistently with magnifier.
-Cons: Shake awake feature is not reliable anymore; when pulling it out of the safe or hitting the range I have to turn on the optic 4 out of 5 times.
Great entry level optic for training and range use. In the past 8 years, I've put over 5000 rounds through this rifle with the HS503G ACSS mounted. Wish the shake awake feature was still reliable but for $200+ I am very happy with this purchase.
Pretty surprised.

Picked this up to try out on a 14.5 inch AR build. Paired it with a HOLOSUN 3x magnifier. I couldn’t be happier. Super clean glass and very very clear reticle. If you have astigmatism like me this red dot will work great.
Great combination of optics and reticle
by Boakye.D. -
I bought this for my SUB2000. It is a very good red dot considering that it comes with the shake awake and sharp ACSS reticle. Although without solar charging, I’m confident with holosun’s battery life. The only thing I don’t like is that there isn’t a memory setting that allows you to turn your previous brightness back on fast, and you would need to click on the +\- keys. But other than that, I love it.
Primary Arms was on it

Thank you so much for the speedy delivery. The Holosun is a awesome optic and I am loving it. I plan on ordering a lot more from Primary
Love it
by Andy -
I’m really impressed with this optic. I have a few other Holosun products and they’re all great. I love this reticle! It’s overkill for my current application but after using it I want to get another for my other rifles. Would love to throw a magnifier on this, I think that chevron would work really well even at 6x

Love it. Bright visible dot. Easy to zero in. Adjustment knobs dust cover has built in tool to adjust. I love it
Great optic, but the caps are the same?
by Johnny -
First of all, this is a great optic from Holosun/PA. I love it.
Second of all, I went to sight it in and took off my end caps to adjust and both end caps read: "UP, R"...... Idk which one is up and down and which one is right and left ? never had this issue before on a new optic.
Great piece of glass
by Chris B -
This is a wonderful collaboration between PA and Holosun!! The reticle is perfect for both CQB and longer shots. The glass is crisp and clear. My only complaint is the center arrow seems to be slightly less crisp than the othe PA optics I have. If the light intensity even the slightest brighter than necessary there seems to be a line form above the center arrow (the red dot). I also wish the optic was etched like other PA products. That being said with some training and use of the optic in differing light situations, this minor issue can be overcome. Please keep this line of products going and improving. I am very excited about this partnership and what the future may hold.
Seems pretty good
by Sleezy E -
From what I’ve seen so far this seems to be a good purchase. Reticle is clear and I can see how having a magnifier would really set this optic off.
Great Sight
by Scott -
This red dot has far exceeded my expectations. The retical is outstanding I absolutely love it. The price is fantastic for what you get. I will be purchasing another one very soon. I'm becoming a believer in Holosun/ Primary Arms great stuff.
