Awesome!

by

Super high quality red dot optic crisp dot. I like the auto wake on/off feature. Works well. I have two now!

Awesome sight!

by

This is a great quality sight period! I like that the battery is hidden underneath the unit sandwiched between the optic and the riser mount. The battery lasts 50K hours so no need to change for a while! The actual dot is VERY bright on the highest setting. I like the auto on/off feature as well. No complaints or regrets here very pleased with this purchase.

Holosun Paralow HS403A

by

I am a retired Military and Civilian SWAT operator and a long time Primary Arms customer. Everything I have bought from PA has worked as advertised. The HS403A that I just got is on my LMT MK18 and it is awesome! It has clear optics and a sharp, crisp dot...I actually replaced my old Aimpoint with the Holosun!! From now on if I want to buy something firearms related I will buy from Primary Arms.

PARALOW

Nice features for the money. There is a faint orange shadow as some have noticed. Pleased so far with the purchase.

There is NO substitute for this sight below $200!Customer service also top notch - I have lost both protective caps on a first shooting -Contacted company and there where sent tome right away and FREE of charge!This is the service we would like to have.

Holosun Paralow Red Dot

by

I bought a red dot from PA and over the years, wore it our and bought another one.Now in that time, my shooting range had changed. 99% of my shooting is within 59 yds.Well I didn't know anything about parallax.So when I bought the new red dot, I couldn't get it zeroed. After much research I learned about parallax. Now PA says their red dots are parallax free OVER 50 yds. Ok that's great but I shoot UNDER 50 yds., so it's no good for me. I needed a parallax free red dot. So I contacted PA and they gave am a RA and paid for the return shipping and sent me a HOlOSUN, no questions asked.THAT folks is TOP NOTCH customer service.

Awsome red dot, Great Deal

by

The Holosun red dot is top notch, perfect sleek clean design and lines, crisp bright 2 MOA dot, the Glass is so Clear that i could not even tell that there was glass there. The buttons are perfectly placed at the top and nice firm detent to the buttons, the riser fits like a glove, i could not be happier,i am going to buy another one! A+

I got a junk one

by

Great concept, was super excited about it. Got it wednesday, put it on the rifle, worked great. About 4 hours later I was playing with it some more and the red dot started to get distorted and only the 3 brightest settings worked. Changed the battery twice. Same story. I didn't drop it or shoot the rifle or put it through any test (cold temp, water, ect...). Hopefully the claims are true and primary arms will send me another one or refund me my money. I really wanted this sight to work and hopefully i just got a bad one that slipped through the QC process.UPDATE: Called PA and they sent me a new one with 2 day shipping, and a free label to return the junk RDS back. New sight works great, hopefully will get out this weekend to zero and run it through its paces. All features on the new one work (auto off, motion sensor wake, ect.) PA has the best customer service I have ever dealt with by far. Great company, hopefully this new sight holds up!

Very good little sight! It has nothing to do $

by

After going through a lot of reviews off AR15.com,I decided to give this "Aimpoint killer" a chance to prove itself.After taking it out to a carbine course in Wisconsin,I have once again found myself proud of my decision with PA.This sight held zero for the two-day course after burning through 1K XM193 5.56 rounds with my trusted PWS.I can't say I beat the jizz out of this little guy, but it has certainly impressed me with its durability and reliability.The battery never died on me, and the dot remained sharp at the medium setting.Although I wish this sight comes with AD QD mount, but I never had to take it off anyway.A lot of fellow trainees were curious about this little sight,as most of them have by now heard of the reputation of Primary Arms. I'm really glad to see a company carries out extensive testing for the products they carry, esp. scopes and red dots.These PA products have slowly changed my impression of Chinese-made products.kudos to PA!

Outstanding RDS

by

I was curious if this RDS was what it purports in the description. Indeed, this optic is awesome so far. I love the auto shut off. I have to lightly hit my rail and then the dot comes back on. The dot is bright, crisp and illuminates perfectly in bright sun light. The glass was surprisingly clear. At this price point, I wasn't expecting the glass to be so clear. The RDS definitely feels like other quality units. And this baby is quite light. Just by adding this RDS and a Mission First Tactical, Minimalist Stock to my system/ I was able to reduce the weight of my rifle by 8.5 oz. It's definitely a sturdy RDS and well worth the price. You won't be disappointed if you're looking for a Micro RD. Aim Point should watch out. As for PA, well they're still the best in products they carry. The prices. And especially their customer service. P.S. Just remember this is a "Micro" RDS. Therefore your lens will be roughly 20mm.

First Thoughts on this RDS

by

I received Red Dot Sight with Lightning Fast shipping.Installed Battery with + side up toward housing(not in manual so got it right first try.)Hope Battery life claim is attained, one of main reasons for buying this Optic.Turned it on and incremented up to highest setting then back to lowest,Dot is nice and tight,with Clear Glass.Accesories are lacking for now and hope are in the Works. QD mount AND KILLFLASH are on my wishlist. Thanks Primary Arms! Giving Four Stars for now until further review.

can't beat the product for the price

by

I recently purchased the holosun to place on a lightweight build I completed. Placed the holosun on the rifle on 5/3/14, sighted it in and on 5/4/14 I ran it through a multi-gun competition at my local gun club. The product worked perfectly. Optic is clear, dot is nice and tight. Held zero throughout competition. Even had fastest time on one stage. Will be purchasing more of these for other rifles. Thanks Primary Arms.

Initial thoughts

by

The optic has clear glass, no bulk, and is very bright. I used this optic on a sunny day with the sun behind me, in front of me, and off the the sides. The results were not good. The red dot is actually plenty bright, very comparable to Aimpoint, surprisingly. However, there is an AWFUL red glare that comes across half of the glass from the 1 o'clock to the 7 o'clock position. This is very noticeable and very distracting to the eye and obstructs the view of targets. This glare so bad that I felt the need to lower my rating from an initial 4 stars (because it isn't waterproof) to only 2 stars. I will be in contact with Primary Arms to see if this is a persisting problem of just a problem with my optic. I will update this review over time.

Fantastifc CS at Primary

Picked up one of these little guys to be a tester. Have yet to make it to the range, but initial inspections have me hopeful.Pros: Build quality seems legit.Battery life is optimisticAuto on is just....coolButtons rather than big dial---better sight pictureWhile we are on sight picture....clear glass. If you were wondering if its better than a TRS-25....yes. Like Holy Crap yes.ConsFew, but that will probably come with range time. The only complaint I have is that the first one I received the w/e adjustment would not engage. So a QC issue in china.....surprise. The good news, I called PA and told them. Keep in mind that this sight was ordered thru my local shop and not by me personally....avoid questions with off duty supervisor....PA sent ME a new one, not the shop, and had a return label with it. Un real customer service.

First impression (Updated 4/12/14)

by

To start with it looks and feels very solid, like it will hold up well. The only thing I've found wrong was the manual sucks. When installing the battery there is a yellow strip that you must lift up to slide the battery, + side up, underneath. Update 1: After spending some time with this RDS There are a couple things to note. While the caps can double as screw drivers they suck at it initially. The turrets are pretty tight initially making it difficult at best to adjust with the little caps, bring a stubby flat head to make it easier. Secondly I found that you need to tap the turrets after making the adjustment to get it to completely set, same process as an real ACOG. Now to the good part. After getting it zeroed I was able to make one big hole at 50yds and a 2 to 3 inch grouping at 100yrds. So was it worth it or not, absolutely! The zero doesn't more and the 2 moa dot is great. With the features of this RDS you can't go wrong, especially at this price point.

Pros: - Glass is very clear (much better than TRS-25)- Dot is crisp and bright (equal to my aimpoints)- Shake to wake fxn works with a brisk lift - The emitter does not occlude your FOV and I'm pretty sure it's low enough to cowitness on an AK w/ UltimakCons:- Manual is Chenglish (probably not PC), says it has a ONE year warranty, and doesn't tell you which way to put the battery (+ side out)- TORX screw on the base... not QD, not flat head, not even an Allen wrench, but the 6-point screw typically used to prevent opening- Wakes to somewhat anemic med-low- Base scratches easily, and~ sloppy assembly with residual sealant on 1 outer edge and internallySummary:- I hate having a torx wrench that I to keep up with- Crisp dot, clear glass, and so far it works great- Obviously not your RD of choice for combat, but if it even comes close to its promises on battery life and durability, then it's a great buy at 1/3 the price of an Aimpoint
