Honestly as good as some expensive dots
I bought this because my Romeo 4x Pro had to go to Sig for RMA work and none of my other red dots worked well on that particular rifle. I just wanted something cheap to use until I got my 4xt back (and I kinda felt like buying something new for fun) I didn’t have high expectations but I was extremely impressed with this red dot. The reticle is as crisp and clear as the ones on my 4xt and AimPoint t2. It really outperforms its price point. One of the main reasons I chose this one in particular is because of the rotary wheel brightness adjustment and lack of a solar panel. The clicks on the wheel are sharp and feel great Now, this obviously isn’t a T2. But it’s pretty dang good for what it is. So what started out as a cheap red dot to throw on a rifle while my nice one was being replaced ended up getting a permanent home on one of my other rifles. I was considering a Holosun 515 but thought that was too similar to my 4xt. Then I was considering a Romeo 5 but I wasn’t a huge fan of the way that looked. I’m just really happy I chose this one.

I hate red dots.
The title explains my opinion of red dots, but this thing is awesome. Very crisp dot that goes June 6, 1944 bright if you want it to. Very nice and tactile~but easy to turn rheostat dial, and out in the daylight it doesn't blur due to my astigmatism like most red dots as long as I don't turn it up excessively bright. The mount that comes with it is trash, spend 15 bucks and get the utg mount for it, that mount is solid and has built in recoil lugs. It also looks nice. The blackish-grayish black finish isn't the most durable, but it's not bad and it wears nicely. Mine has some minor wear and I beat it around all over the place. Best red dot for the money imo and has been absolutely awesome. I still have some mbus sights for backup because I don't trust electronics, but this thing has been great.

Excellent optic and investment.
Excellent optic for the price. Holosun in my opinion has some of the best bang for your buck optics on the market. Dust water and shockproof, hold zero, and have been very durable in my experience. Work well with or without magnification, and match up with most mounts and magnifiers. Not a $70 no name red dot that you will replace in a few range sessions

Fantastic
You could pay a lot more for a red dot. But why? Holosun continues to put out products that compete with the major competitors at a fraction of the price. I’ve been running this optic on a MK18 for about a year now and have had no issues whatsoever. I ran it through 40 hour SWAT school where my rifle was put through the ringer. It’s been dropped, kicked, dragged, and continues to hold zero. With an advertised battery life of 100,000 hours it beats red dots at 3-4 times the price. On 9-10 power the dot is clearly visible even on the brightest days. The people complaining about the battery cap scratching are not doing any real training. Your rifle/optic should have scratches on it…. If you want a red dot that will handle anything you throw at it without breaking the bank, pick one up. Holosun nailed it with this one.

incredible sight, but you already knew that
does just what it says on the tin, so simple, so great. Love the increase to rated battery life, I never worry when I pull the sight out and it was left on. I also love the turret caps for both having a notch to adjust the turrets, and for putting that notch on the same-line as the labels on the inside, making them faster & easier to line up with the turret slots. Incredible sight, and for the money, a steal!

Great sight
Excellent sighting system. I have the 503c red dot on a 1301 12 gauge and love it. If it would have had the solar panels on the top it would have been a 5 star rating. The gold dot is very easy on the eyes especially in low light conditions and it doesn't wash out in bright daylight (even in desert environments).

A Big Step Up from TRS-25
This HS403R replaced a TRS-25 on my 9mm CX4 storm. It sits higher at ~2.1 in. above the bore vs. ~1.75 for the Bushnell - more comfortable in my opinion. The dot is crisp and the glass is clear by comparison to the TRS-25. It was easy to mount and zero. Clicks were positive and seemed precise at .5 MOA. I zeroed at 20 yards (147gr HST) so I figured 10 clicks per inch, and that seemed right on. Im sure the HS403R is capable of more than I will ever subject it to in an HD role. If the battery life is anywhere near advertized, I am confident it will be ready if I ever have the need. I feel this was worth the extra $$$.

Amazing budget optic.
Did everything it needed to, unfortunately the person it was for had a astigmatism, and saw bursts instead of a dot. I saw a dot perfectly but it was returned as unusable for them. Holosun has changed the game of weapon optics, going to get her the 65 moa circle with dot as that will show fine even with astigmatism. 100k batter hour life is amazing, and the dot is as fine and crisp as youd need it to be.

マーベリックGen1からのステップアップは正解
マーベリックのGen3に買い替えようかと思っていたのですが、思い切ってホロサンに買い替えました。 価格は、倍以上違うので性能が良くて当たり前なのですが、満足出来る逸品でした。 所有するT1タイプのドットサイト「マーベリックGen1」「マークスHD5 Stinger」との比較になりますが メリット ・質感はよくハイマウントもしっかり装着できる。実銃対応は間違いないと思える。 ・輝度調整ダイヤルは、マーベリック、HD5よりも軽く、バッテリーキャップが緩むことはない。 ・レンズ口径20mmなのにマーベリック、HD5より大きく見やすい。 ・LED発光モジュールが目立たず邪魔にならない位置にある。マーベリックGen1は、ここが難点だった。 デメリット ・価格が高い。安くなっても2万円弱。コストパフォーマンスがよくない。 ・お座敷シューターなので関係ないですが、T1タイプのレンズプロテクターのサイズが合わないようです。
