Holosun HS403C AR15 Red Dot Review & Rifle Test Fit

Table top review of the Holosun HS403C AR-15 Red Dot with solar power option. A excellent sub $200 red dot sight that includes 1/3rd and low mount risers.

I lost one of the screws as I was trying to put the battery in. Sadly thank God it came with the other tray

[@AnthonyyVanessa_]

Good review!

[@exo32582]

Nice might look in to that

[@DB-rg2dk]

Thanks for the review, I purchased one because of its mounting height, not to co witness, but to be able to use the irons underneath the red dot housing, my AR has a slightly raised rail where the carry handle would normally be, and it was enough to clear the irons as a back up.

[@reliablethreat23]

That's called "lower 1/3 co-witness"

[@DB-rg2dk]

@@reliablethreat23 I'm pretty sure co witness is when you can see the iron sights inside the red dot glass, 1/3rd from the bottom of the circle to the center of the dot. Mine is not a co witness because I can not see both sights at the same time. Technically I am using irons as a back up.

[@reliablethreat23]

@@DB-rg2dk Exactly. "Lower 1/3 co-witness" is when the optic sits higher than the iron sights. The red dot floats above the front sight post rather than directly lining up with it.

[@reliablethreat23]

@@DB-rg2dk "Absolute co-witness" is when the iron sights line up with the red dot.

[@DB-rg2dk]

@@reliablethreat23 yeah you aren't getting what I'm saying, my red dot optic sits completely above the irons line of sight, if I am looking thru the irons, I'm looking thru the mounting bracket under the red dot. That's how high my Holo sits.

[@Kyman23]

I am near sighted too. Can’t see far/a foot or more in front of me without contacts or glasses. Where do you position the optic on the pict. rail? I think towards front of barrel is better (further from my eyes). But I’m looking for others w similar situations feedback. Thanks!

I HAVE A HOLOSUN HS515CU AND LOVE IT.PAID 265.00 FOR MINE.IT IS WORTH THE MONEY BUT I WISH IT WAS MORE WATER PROOF.

[@JoeOfAllTrades]

does this have shake awake?

[@giannidemarchi9095]

I was not expect that the holosun was made in china as I can read below the mount...is this the original holosun?Because I want to buy one but I'm not sure

[@2phast]

The sight and riser are both made in China. Good quality stuff!

[@doomfathertm8771]

How do you know if it is on battery or solar mode?

[@darkimperial007]

The buttons wont adjust the brightness if its on solar

[@doomfathertm8771]

@@darkimperial007 thanks

[@breantargaryen2630]

does it increase magnification for longer ranges???

[@2phast]

Red dots like these don't provide any magnification. You could use a flip to side magnifier, if you need magnification.

[@McFartsnatcher]

I know this is an old comment, but I bought a tacticon magnifier for around $70 and it alined perfectly with the Holosun (shown in this video). I wanted to see if it works, especially being so cheap, and it's held up great so far. Cheers!

[@sunnycat69]

hiw do you like it vs the pa advanced micro red dot

[@moderngunguy3666]

Kevin Greenleaf holosun makes the primary arms Red Dot so they are exactly the same

[@sunnycat69]

Modern gun guy not necessarily primary arms announced the next-gen in their Advanced Micro Red Dot it's supposed to be way more weather and they went with the knob style brightness controls instead of buttons also even more of a low pro emitter and better glass as in no blue tint

[@moderngunguy3666]

No Holosun is better than primary arms or the same. Holosun also has a whole new line out now it's probably the same one that they sold to primary arms either way holosun makes there red dots

[@2phast]

The existing PA MD-ADS red dot does not have a blue tint to it. The new PA red dot is actually still under development and no pre-production units are available yet, when they are, you will get to see it first on my channel. FWIW, PA has no production facilities to build their own sights.

[@doro19]

Primary Arms AMD sight is made by Holosun to PA specifications. 'Nuff said.

[@daveenoch575]

Are the lens supposed to be not straight?

[@reliablethreat23]

Yes. They are slanted by design to reduce glare.

[@b-rad6978]

yes it is by design, very very good sights. better bang for the buck than aimpoint t2.

[@TheJennflip]

I have a Holosun on a CZ with the 2moa and it is a small dot--- must be the filming because the dot here looks as big as a pencil eraser!!!!

[@zachmccausland1157]

I was thinking the same thing! I was wondering if mine was advertised as a 2moa and really a 1moa 🧐

[@FlyGuyF119]

I was all about this and about to buy one until I saw that stamp at the bottom...... "Chinesium".......
