A red dot to end all red dots

by

This red dot delivers from every angle. The unlimited eye relief is amazing along with the glass. It’s super compact I. Size and adds practically no weight to my rifle at all. It adjusts to any light conditions and easily switches between battery and solar. Every one of my carbines will Be topped off with a holosun

Great Little Red Dot

by -

Great purchase, delivery and customer service. I really enjoyed the functionality of this Little Holosun HS503CU. Using on 9mm PCC quick and easy to find the dot on the move.

Easy on the eyes with a circle dot.

by -

I have had problems looking and aligning with just a red dot. This circle dot is easier and more resting with my eyes to see and align the target. Worth the extra money.

Great optic

Pros:
<br>1. Reticle
<br>2. Price
<br>3. Battery life
<br>
<br>Cons:
<br>1. A little too big.
<br>2. Special tool (mini screwdriver) needed to remove battery.
<br>3. China
<br>
<br>I want to dislike China but they did well with these products. Battery life, reticle design for this price is wonderful. Unit is a little big but I’m sure they will shrink them down in the coming years. Mounted this on my .22. Probably won’t have to change the battery for many years. Love the solar panel on top. Wish Trijicon and other US manufactures would up their game. Guess good old fashioned competition drives innovation and Holosun will force US manufactures to up their game, and I’ll be ready with my cash in hand.

Holosun red dots have been awesome.

This is the third HS503CU red dot that I have purchased and this last one is a spare for another potential FAL build. I love the Multiple Reticle System but particularily the 65 moa circle and 2moa dot reticle. So far I now have 7 Holosun red dot sights with this reticle pattern and they have proven to be excellent values and they have held up very well. I have not experienced any issues with the red dot or red ring reticle blurring or blooming out due to my aging 62 year old vision with an astigmatism. The only thing I don't like on this model of red dot is the battery tray that uses tiny,tiny little fine threaded torx screws. If you don't have the provided tool or the torx head screw or tiny tool bit strips out and you need to change out the battery you are screwed. I really preferred the discontinued model (HS503GU) with the side mounted no tool required screw on battery cap. I took off one rating star due to this poor design issue. Primary Arms service and delivery were awesome.

Nice!!!!

One of the best optics for the money. Didn't know if I would like the holosun brand but after multiple purchases I guess you can say they've grown on me because I've bought like 4/5 of them. Don't hesitate to buy unless you wanna come out of pocket for the more known name brand products.

Right height for high stock guns

1. Good sight with nice features. I really like the circle dot reticle.
<br>2. The instruction pic of the installed battery is misleading. The plus side goes down.
<br>3. I'd vote for larger screws on the battery tray. Teeny tiny. Push the tray in as far as it will go before trying to tighten.
<br>4. I'd vote for a lens shade......
