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.

Great for the Price

Overall seems to be a quality built optic. It feels great, looks great, and has a ton of features for its price point. Only 2 minor things I don’t like, the emitter is visible through the glass and the turrets don’t have an audible click when adjust windage and elevation. Other than that a solid offering from AT3

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

Good budget Optic

Overall the Alpha is a great optic for the money. I only wish the adjustments had the audible click and that the emitter mount wasn’t visible in the glass.
