About the ALPHA Red Dot Sight

AT3’s First Shake Awake Red – or Green – Dot Sight

The ALPHA represents the best – value, features, and usability – that you can expect from an AT3 red dot sight. This red dot sight is perfect for the AR-15, and ready to mount up to your favorite rifle right out of the box. With a true 50,000 hour battery life and Shake Awake to extend that life into years more, the ALPHA is a reliable companion to your AR-15.

And new for 2024, we’re offering our first green reticle version of this rugged, reliable, and accurate red dot sight. We loaded in all the same functionality to the green version; Shake Awake, long battery life, and a crisp reticle for accuracy at any range. The human eye picks up green easier than it does red, meaning you can find your reticle and your target even faster.

But let’s say you’re an AK guy, or just looking for a no-fuss optic to mount on your favorite rifle. The ALPHA comes with a variety of mounting solutions, and features an Aimpoint Micro mounting pattern for wealth of aftermarket compatibility. The rugged, capless adjustment turrets are 1/2 MOA adjustable, and this thing holds zero. Period. Even sending .50 BMG downrange doesn’t phase the ALPHA.

Ready When You Are, No Matter The Mission

  • Shake Awake technology turns the sight off after 15 minutes with no movement – and comes back on when you move it again
  • High-efficiency LED gives the sight 50,000+ hours of life before factoring in the battery-saving Shake Awake
  • 2 Night Vision and 9 Daylight brightness settings, giving you the right option from total darkness to stark daylight
  • Top-mounted brightness dial is easy to adjust for any shooter, regardless if you’re left or right handed
  • 1/2 MOA capless windage and elevation turrets are easy to adjust with a coin, flathead, or even a spent casing

Multiple Configurations for AR-15s and More

  • Comes out of the box with an Absolute Cowitness Riser Mount already attached – just put in the battery, mount it to your AR, and start shooting
  • Includes a spacer and extra hardware for Lower 1/3 Cowitness, so you don’t have to shell out for extra mounts to find your preferred height
  • Forward cantilever on the riser mount pushes the optic further from your eye, funneling your vision into the tube so you can find the dot quicker
  • Easily mounts to a wide variety of guns using the included Low Mount, which is perfect for AKs, 10/22s, MP5s, and many more
  • The Aimpoint Micro (T1 and T2) mounting pattern means you have tons of options for alternative mounting solutions, like AK side rails and 45 degree mounts

Guaranteed Reliability and Lifetime Warranty

  • The ALPHA’s housing and mount is rugged, yet light in weight, making it a field-ready companion for your rifle
  • Tested for recoil in 5.56, .308, 12 gauge, and stepped all the way up to .50 BMG; the ALPHA will hold its zero
  • Multicoated, scratch-resistant lenses produce a clear, vibrant image of your target, and keep your reticle crisp
  • Nitrogen purged housing is fogproof and IPX7 waterproof, making it sealed against the elements
  • Backed with AT3’s fully transferable Lifetime Warranty – even if you’re not the first to own it, we stand by our product

Frequently Asked Questions

Q: Red Dot or Green Dot? Which version is right for me?
A: This is heavily dependent on personal preference. Both versions of the ALPHA can reach daylight levels of brightness for visibility. Traditional red dots have greater contrast against most environments, but may be harder to “pick up” in your field of vision. Green dot sights may have lower contrast to green foliage, but green reticles are generally easier to pick up for the human eye, in how we perceive the visible light spectrum. If you’ve been dissatisfied with red dots in the past, give the green reticle a shot; it may make a world of difference for you.

Nice combo just didn’t work for me

Never was able to get a round dot look thru the 4X magnifier. Kept the red dot sent back the magnifier. Thanks

Was Skeptical - Not anymore

Bought for my latest AR/5.56 thinking I’d give this setup a try as a way to save a little money and lo and behold…it works great, was relatively quick to get on target and accurate. Easy to install and the shake-to-wake works perfectly. Great piece for the money.

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

AT3 and 4x Magnifier

Super fast service. Had an issue with the magnifier centering. Sent an email and was advised that they had had some occasional issues with the mount. Sent me a replacement that arrived quicker than the original order and this solved the issue. If the products are anything like customer service, you can’t go wrong.

Thank you for your positive review of our AT3 Alpha + 4xRDM Red Dot Kit! We're glad to hear that you were satisfied with the quality of our products and the fast service that we provide. We hope you'll continue to use our products and recommend us to your friends. Thank you again!

Red dot = 5*, 4x = 3*

I give the red dot a solid 5 stars. The 4x magnifer is okay. Unlike the three 3x magnifiers I bought from AT3, this 4x is not as ergonomic in its flip mechanism. You have to press a button with your left hand (or get real good at the one hand technique). Your others allow one to pull back and flip all with one hand.

Loose

I have sent 2 emails asking about the magnifier being loose at the swivel point but have not received a response.
