3-Pack - Magpul PMAG 30-Round M2 MOE Mag - .223 / 5.56 NATO - MAG571
Streamlight Protac 2.0 Rechargable 2000 Lumen Weapon Light Kit
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 the ALPHA and DELTA 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.
