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.
