    • Rock‑Solid Performance and Zero Hassle Installation
Color: Red Style: Multi-Reticle
This Holosun ARO‑CORE Series sight absolutely exceeded expectations. The package showed up earlier than expected and was in perfect condition; no dents, no scratches, nothing out of place. Installation was a breeze; it mounted securely and aligned quickly without any frustration. Once on, the clarity and responsiveness were immediately noticeable. It feels durable, performs flawlessly, and genuinely elevates the setup. Worth every penny and then some. ... show more

    • You get what you.pay for!
Color: Red Style: Multi-Reticle
I like the three reticle version. be careful on sales items as you need to check they make a single red dot and they make a 3 reticle version. also, why would HOLOSUN no add the low mount like everyone else does. it has a T-1 footprint! so it smart to give or add it in. I had to pay close to 60.00 for the low mount so I can mount it on my Turkanelli M-4. so I actually had to buy two as I bought two.of these on sale. it was a mirical that I got the ARO with three reticles. nice clea glass, sharp reticle. you can adjust it way out if you need to. and its 1x1 power not 1.25x or somwthing thats suppose to be 1x I love it. just PO that I got stuck loosing out on a good deal by having to purchase the low counts. not funny Holoson. just kinda sleezy now eveeytime I consider purchasing a Holosun I will have to go through the bologna of asking the seller.to.open box and checking. I will admit the T-1 style low mounts come with two heavy screws, so the sight won't slide back and forth, as.there don't come with a Picatinny Tight fit lug on bottom. still slides back and forth a little but the two screws keeps it pretty darn tight. ... show more

Color: Gold Style: Multi-Reticle
Hands down my new favorite optic! I have several red and green dot optics, but I REALLY like this gold dot! Easy to install, seems very sturdy, and the dot is crisp!

    • Best optics for the money
Color: Green Style: Multi-Reticle
Extremely good radical the optics are amazing battery. Life is amazing. I bought at least seven of these optics and I’ve never had a problem. I do beat them up a little bit and they still work.

    • Excellent optic
Color: Green Style: Multi-Reticle
I purchased a cheaper green dot and I couldn't get my rifle to zero . I spent time and money and tried everything but I couldn't zero my rifle. I purchased this green dot and zero was achieved in a flash!! It's so true, you get what you pay for, cheap is dear and all the other cliches!

    • An awesome optic for the money
Color: Green Style: Multi-Reticle
I purchased the green reticle version since it’s easier for me to see in daylight. The 65 MOA circle is helpful and the sight picture is clear as day. No issues with battery life and it’s still holding zero after multiple sessions at the range.

    • Limited to Single Dot, and Dot With Circle; No Circle Alone
Color: Green Style: Multi-Reticle
Only one thing lacking: the ability to have a circle-only reticle. You can have a single center dot, or a circle with the dot in the middle, but not a circle only. The green, for me, is easier to find than red. Really like it. I like the shake-awake feature -- saves the CR2032 battery and is always ready. Battery is easy to change but the T10 Torx screws are tiny. Good news: they supply extras in case you lose them. Many brightness levels. Easy to zero, easy to mount -- torque to 30 inch-pounds. ... show more
