You get what you pay for

U was browsing the internet when I came across this open box red dot sight for around $60. With a coupon code I got it for under $55. I saw it new for around $70 and could have forked over another $10 but why? Right? Absolutely right. I got it and it looks brand new. There was something about shutoff issue on the bag but it comes on and goes off on demand. I installed it on my Ar with no issues and it works great thus far. I've yet to get out to the range and test zero but I'm highly optimistic that I won't have any negatives about this little guy. I took a big infinity scope off and when I did a ton of weight went with it. I'm way more mobile and a lot quicker now. Pay for it, get it, enjoy it.

Thanks for sharing your feedback, Albert. We're glad you're satisfied with your purchase. Cheers!

Great sight at a great price

I got a really good deal on this sight because it was an open box return. I also had a coupon so I only paid $53.99 for it and shipping was free.
The description of the sight said because it was an open box return it might have blemishes and/or scratches but would be in perfect working order.
Well not only does it work just fine, but I don't see a blemish or scratch on mine. It looks brand new.
I just needed to attach it to a 1" cowitness riser because I have BUIS. I popped the included battery in it and had it zeroed in a few minutes. It's very easy to adjust via windage and elevation nobs. The nobs seem to have very tight tolerances, for exact adjustments. This sight amazes me for it's quality, even at the regular price of $74.99. I have friends that have paid a lot more for the same or less quality sights.
I also had a question about the sight and the response was very fast, excellent customer service.
I highly recommend this company and this product. Thanks AT3!

Thanks for sharing your feedback, E.R. We're glad you're satisfied with your purchase. Cheers!

Remarkable

I’ve been shooting for 35 years. Shooting to eat, to survive and in completion. I can honestly say, I did not expect such a clear and precise sight at this price point.

I’ve shot almost all of the big name brands, and a few budget brands. I believe we truly live in a time where budget optics are worth every penny and then some.

I put this AT3 optic on a shotgun to test it. I had a several boxes of slug and buckshot and I needed some range time. Mounted this AT3 sight, and was zeroed in under 5 rounds. I then ran through 200 rounds of buckshot and slug throughout the day. The AT3 sight held zero and was amazingly clear in sunlight and low light conditions.

I then placed the same optic on a suppressed 10/22. Zeroed the sight with minimal rounds and started having fun. It’s my basic 10/22 worth a Jard trigger and is basically my truck gun. I purposefully dropped my unloaded 10/22 a few times, both on the sight and just on the butt stock from 18” to 4 feet. STILL HELD ZERO!! When I get to do some suppressed steel shooting, I tend to get carried away and I ran through 400 rounds that evening. I even took the gun with the AT3 mounted on some light varmint hunting and cleared out a few pests. Out-freaking-standing!

Great optic, amazing price, and these folks support our military and first responders. Take the plunge, you won’t regret it.

Thanks for sharing your experience, William. We work hard to meet expectations like yours, we're glad we hit the mark for you. Cheers!
