About the ALPHA Red Dot Sight with Shake Awake

AT3’s First Shake Awake Red 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.

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
  • 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
  • 9 Daylight brightness settings and 2 Night Vision compatible settings, giving you a full range of options for ambient lighting
    Note: The ALPHA is not a night vision device. Settings 1 and 2 are designed to be used when you are using night vision devices, as to not overwhelm or damage image intensifier tubes

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: What is Absolute and Lower 1/3 Cowitness? How do I set up my ALPHA for either?

A: When you take your ALPHA out of the box, it will have the riser mount attached for Absolute Cowitness configuration. This means the dot will be aligned with standard iron sights, and placed at the same center height. If you want to run iron sights always deployed, you may opt for Lower 1/3 Cowitness. All you need to do is take out the four screws in the bottom of the mount, insert the spacer, and screw in the four longer screws included in your sight’s packaging.

Most people prefer Absolute Cowitness as a matter of comfort – but Lower 1/3 cowitness is popular because it allows more versatility with iron sights.

Q: Do I need to use iron sights along with with the ALPHA Red Dot Sight
A: NO – Iron sights are not required to use this red dot sight! The red dot sight can be used on its own. Many people choose to use iron sights as a backup, but they are optional. This red dot sight will work great on “optics ready” rifles that don’t have any iron sights.

About the DELTA 3X Red Dot Magnifier

The DELTA has better glass clarity, longer eye relief, and an excellent QD mount!

The DELTA is AT3’s new red dot magnifier, boasting a long 3 inch eye relief, a broad field of view, and enhanced clarity for making accurate, long-range shots with your red dot sight. This magnifier works with any red dot sight with absolute or lower 1/3 cowitness using the included spacer, making it perfect for enhancing your AR-15. Plus, you can swap this magnifier between rifles easily with the included quick detach mount, with a ratcheting adjustment that ensures a tight, secure fit on your rail.

We recommend pairing the DELTA with our ALPHA red dot sight, for a fully featured, modern red dot and magnifier setup. You can get them as a set here, with a bundle discount to enhance your rifle, and prepare you for any shot from point blank to 500 yards or more!

Better Eye Relief and Sight Picture

  • A full three inches of eye relief ensures you’ll have a clearer view of the target, even with backup iron sights installed!
  • Multicoated glass gives you a more crisp view of your target, with better light transmission and definition.
  • 38 foot field of view gives you a clear picture of what’s around your target, with a forgiving eyebox for head movement.

Flexibility Between Rifles

  • The Quick Detach Mount is our best yet, with an audible ratcheting adjustment for tight, consistent installation.
  • Switch the Delta between multiple rifles with the fast QD lever, and ensure your red dots have magnification when you need it.
  • Out of the box Absolute Cowitness height – and with the Cowitness Spacer, Lower 1/3 Cowitness for even more optics compatibility.

Durable and Rugged

  • Solid steel lockup in the mount keeps the magnifier secure without the need for a release button or lever.
  • Rubberized shroud keeps the magnifier protected from bumps and scratches in the field.
  • Durable enough to handle recoil from high caliber rifles, shotguns, and even .50 BMG. Yeah, we went there.
  • For anything else, you’re covered under AT3’s Lifetime Warranty. If there’s an issue, we’ll take care of you.

Strong Warranty + Excellent Customer Service Company = Solid Budget Optics

Not the first thing I've bought from AT3, and won't be the last.

Running in at half the price of the top end optics in the same family, the Alpha+Delta combo set gets you running with money left over for ammo. AT3 is a trustworthy group of dudes in Minnesota, which you get for free.

Don't buy this if you are the type to get all worked up over brand logos and name recognition; but if all you care about is performance and reliability, run with this setup & use the spare cash on ammo.

AT3™ ALPHA + DELTA Red Dot Kit

Great products at a great price! Shipped fast. Just what my new AR needed. Will be buying more from AT3.

Thanks for the review! We're glad you're enjoying our products.

James H.
Great combo!

I just sighted in my back up iron on my rifle and co witnessed the alpha Red Dot, and it was fantastic! I used the Delta magnifier at 100 yards and it was really clear. Great products! Glad they are USA local. And the videos on how to install are so helpful. And really thank you Randy for the 45 min optics Bible video! So informative. I'll be back.

Tyler Tenery
Exactly what I expected

This optic combo came right out of the box ready to put some hot metal right down the range. It was quick to get zero'd in, and the adjustability of the dot is perfect. I couldn't be more satisfied.

Thank you for the positive review! We are thrilled to hear that our product met your expectations and performed well at the range. Our team takes pride in providing high-quality optics and we are happy to hear that you were satisfied with the adjustability of the dot. We hope you continue to enjoy using the AT3™ ALPHA + DELTA Red Dot Kit. Happy shooting!
