Holosun Paralow HS503G Red Dot Sight - ACSS CQB Reticle

First time use review with 300 rounds after 25 meter zero with Federal 5.556 55gr:
<br>
<br>The reticle is very clean, with every setting for any light condition you could possibly want. It has the sleep setting and the reticle will automatically turn on with movement. I bought this optic specifically for the reticle design, but was hesitant to go with Holosun. I will say an skepticism I had is gone. The optic hasn't disappointed at distances over 100 yards. Next purchase with most likely be a magnifier. I highly recommend this optic if you choose not to go Eotech or Trijicon. Great collaboration between Holosun and PA with amazing price point!

<br>Will update review after more training time.

Works great on my Ruger 9mm PC Carbine. The ACSS reticle is supposed to work fine with this caliber, comes with illustration, sight it in at 25 yards for chevron top, and dots correlate to 50 100, 150 and 200 yards. Right now it's mounted about mid-rail, and the reticle is noticeably small, those little dots don't show up, so i'll try if closer to my eye and see if I can discern the details better so it will be more usable. I can see why a 3x multiplier might be a great option, but I don't want that on my Ruger.

This is a really amazing optic. The battery life is outstanding. The toughness of Holosun and this red dot in particular has been proven several times over by independent users all over the net. The reticle itself is bright and tight. It's super sharp and will get way brighter than you need it to. The shake awake feature is great and works well. I was able to zero it quickly and the glass looks completely flawless in my unprofessional opinion. Everything I want is there without it feeling cluttered. It's hard to beat a package like that. You would have to really try to break one of these and I can't really envision a realistic situation where one of these would fail that wouldn't also torpedo a much more expensive option. If you're looking for a red dot in this price range but you don't want to sacrifice on quality I think you'd be hard pressed to find a better option.

The best red dot I’ve used to date. For the price you cannot beat this. The reticle is very useful and easy to use helping me to hit plates out to 600 yards easily with an mk18

Best red dot out there regardless of price. I would buy it for all of my guns that currently have a red dot. Pair it with a magnifier and this little red dot beats out most lpvo. Easy to use. Illuminations works very well during the day. I would highly recommend.

I was very sceptical about this optic as I had never heard of it before. I took a chance and so far am very pleased. It is as advertised. I have it setting on an AK and work very well on it. It would be nice if the Chevron was a bit larger and the front lens set slightly farther in to protect it.

The worst thing about the HS503G is that it makes me want to replace my T1 and H1 Aimpoints. The CQB horseshoe is fast at CQB distances with varying light, backgrounds and target colors - easier than finding a dot. I was wrong about writing the horseshoe off. I find the chevron superior to the dot as well when ranging out beyond 50 yards.

Pros:
<br>Lightweight
<br>Solid Construction
<br>Includes two bases/mounts
<br>ACSS reticle!!!!
<br>Inexpensive
<br>
<br>Cons:
<br>ACSS reticle is a little small, but what can you expect, it’s a micro red dot after all.

This is a great sight for the money. I have purchased two and will purchase more down the road. Works especially good when paired with a magnifier.

This sight is awesome! I have some astigmatism so most red dots are fuzzy to me. Even the expensive brands like aimpoint look like a star burst. This sight is much easier to see when paired with a 3x magnifier. The reticle is very small without the magnifier. If you buy this you NEED a 3x magnifier. Thanks PA!

I finally got to use my new Holosun with ACSS, after a long wait. When I got it, I was convinced i wasn't going to like it because of the reticle being so small. But at the range, all that went away, and it really proved to be a great red dot. I had no problems sighting with it, and even though a magnifier would make this top notch for distance (in its class of course), it wasn't at all necessary for 100 meters or less.
<br>Also, I had no problems seeing it in the full sun, with the setting on 4 or 5. Great optic, and I can't wait to put a magnifier behind it. Primary Arms delivers as always. (And Holosun, gotta give them their props too)

If you have an astigmatism then this optic is not for you... If not, it is a really nice little red dot. I have an astigmatism and never really had an issue with a red dot before, maybe a little splaying but never enough to make me not accurate. Initially looking into this optic, my eye just made it a blurry mess. I thought it was a bad optic until i looked at it through a magnifier and it was crisp and excellent. Flip the magnifier and instantly blurry. Keep this in mind if you buy this optic, it may be your eyes that are the issue.

Everything works as advertised, and this unit is a great value. I had never used a red dot before, and it took my eyes a few minutes to adjust.
<br>The size of the chevron is a bit of a double edged sword. It's pretty tiny, which makes it very accurate, but hard to see the details of unless you're sitting perfectly still.
<br>In the end, I'm shooting tight groups out to 100yrds with no magnification. It holds zero, has a light setting for every condition, doesn't blur when you turn the light up, and is very easy to adjust. For this price, you couldn't ask for much more.

I have two of these now and like them a lot; one using the supplied mount and the other using a Holosun absolute co-witness mount on an AR15. No issues with either mount. My only criticism (and it's not really one) is that the reticle is so fine (1moa) that it's not very useful at 100+ yards. Problem solved with a flip-to-side magnifier. Will probably buy more of these in the future.

The red dot sight itself is great, but the mount is terrible. First range trip with the sight saw the screw connecting the mount to the rail snap right in half. It was properly torqued with blue loctite. I then used the screw from the second mount that comes in the box figuring this was a freak occurrence, torqued with blue loctite. I let it cure, then I come back to it a week later, and just the force of charging the rifle snapped this second mount screw (before I fired any shots). Very disappointed in the mounts, particularly the screws, that ship with this product.

I just received this today and nothing worked as it should. The chevron was blurry and there were two lines of dots very blurry and the horseshoe would not come on. It seems there is no Quality Control thru Primary Arms and they are sending out goods made in China without checking them for function. I'm sending it back and requesting that the new one has a note in the box saying it was functioning properly. The box it came in had no seals on it, so it should not be too much of a problem to open them and make sure they work before sending them out.

<br>From PA: Although this is branded Holosun, it has our reticle so we do check 100% of them. The horseshoe comes on separately and you will find instructions in the manual. Or give us a call. We want you to be 100% happy with the sight.

I own several of these sights and all have performed exceptionally well. Just ordered another one one sale. Glass is clear, reticle is sharp and the hardware is rugged. AR's, SBR's, Shotguns... loving a quality optic that's affordable enough that I can have the same sights on multiple guns. Thanks PA!

Over the last several months I have ordered 10 of these scopes.
<br>6 of the ten scopes have not had the horseshoe in the reticle.
<br>I think I will be sticking with the primary arms brand from now on.

The micro chevron reticle is quite small, which is a benefit as it provides extra precision. I'm using it with a flip-out magnifier on an AR9 and it works great. I like how many levels of brightness this red dot has, and the fact that it has motion sensing so you can basically leave it on all the time.

Did a great deal of reading and YouTube research before going with this optic. I'm candidly thrilled with the capability of precision. I'm using it without the magnifier and shooting 1 MOA dependably. And yes, the reticle is small, but very usable. Great battery life.

GOOD<br>- ACSS reticle in a red dot is basically the best thing ever. This reticle is perfect. In fact, I hope Aimpoint/Trijicon puts this in their small red dots. Combined w/ a magnifier, this is a seriously great carbine optic<br>- Battery life - I've had mine on for over 7 months now (with the horseshoe on for most of that). No noticeable dimming. Seems to be as advertised.<br>- Nice mount - Screw requires a T10 torx, but it is very repeatable and holds zero. Taken it off and put it back on more than 20 times and it stays true.<br>- Bright day daytime visible<br><br>BAD<br>- Squishy wind & elev. YMMV, but my elev knob in particular has almost no positive clicks as it is turned. It's usable, it holds zero, and adjustments are 1/2 MOA. However, it is very squishy and sometimes there is no click at all. This is not a deal killer by any means, but this is where the price point shows, and is also why I didn't give the HS503G 5 stars.<br>- No retention for windage/elevation caps. These are easy to lose.

Initially very excited about this optic. Clarity was great and more crisp than other red dots I own. However with only 200 rounds of 556 something must have shaken a circuit loose in the optic because it is no longer functioning. A battery change did not fix the problem. Sent it back to PA hoping I just got a dud unit. Hopefully a more positive review will follow with the replacement unit.

Wow!! Simply awesome. Hard to believe the couple of poor reviews. Mine is much better that what I expected for $220. I'm sure there are a few bad ones but Primary Arms will fix that in a hurry so its hard to believe.

Pros<br>- Stands up to hard abuse.<br>- Horseshoe makes a night and day difference for CQB target acquisition<br>- Looks great through Night Vision<br>- Works great for 5.56 and .308. Works even better for .300 BO<br>Cons<br>-Slight orange glare if the sun hits it just right while a witch is performing a spell to try and through you off your game<br><br>If you're thinking about spending money on an Aimpoint, Trijicon, or Eotech, then don't. You're reading this review because you're having second thoughts about spending that much money on an optic, so buy this Holosun instead. The glass and reticle are incredibly clear. The horseshoe does a better job for CQB than Eotech, the ACSS reticle does as good of a job as a Trijiconfor reaching out, and the battery life is on par with an aimpoint. If you're worried about ruggedness, then don't. This sight has been run through the gauntlet and the dings and dents I have put in it have not caused it to lose zero once or not turn on.

While this is a budget friendly optic, the build quality is exceptional for the price point. I beat up my optics by throwing them in my bags, accidently dropping my firearms, tossing multiple firearms and items in my bags. I travel to and from indoor and outdoor ranges in temperatures ranging from 10f to 105f and not once during my year of ownership has my original 50/200 zero strayed or been lost on any of my Holosun optics. In my year of ownership, I have not yet needed to change my battery.
<br>
<br>The lens objective is 20mm. The glass is clear with little to no blue/green tint and handles sun glare extremely well during my bright outdoor shooting adventures. The reticle brightness even goes plenty bright to shoot outdoors in the bright sun during any time of the day. I seriously have no complaints on how it handles the sun. Both (to my eyes) seem to be a true 1x for magnification.
<br>
<br>Seriously, I'm a huge fan of Holosun and sold my Trijicon MROs and Aimpoint's for these.
