Inside the box



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!

XTREME Returns

As a small business, we face a choice: we can either raise all of our prices to cover the cost of returns, or we can keep our prices low and offer an optional Return Guarantee. We chose the second option because it's fairer to you. That $5 goes directly toward the logistics of a pre-paid return, meaning you get a "no-questions-asked" experience without us having to inflate the cost of every item in our shop. It keeps us independent and keeps your wallet happy. When you shop with us, your order isn’t just a number—it’s handled by a small team that cares about the gear we sell. Because we don't have the massive overhead of a giant company, we use this $5 guarantee to bridge the gap. It provides you with a pre-paid, priority return path, ensuring that if you need to send something back, we can process it immediately and get your refund or exchange moving. Thank you so much for understanding.
