AT3 Tactical Delta 3X Red Dot Magnifier with QD Mount

SUPERIOR EYE RELIEF - A full three inches of eye relief ensures you'll have a clearer view of the target, even with backup iron sights installed! CLEAR OPTICS - Multicoated glass gives you a more crisp view of your target, with better light transmission and definition. SMOOTH FLIP TO SIDE - No buttons or releases needed - just push the magnifier to the side when you don't it, and pull it back when you do. SECURE AND FAST QD MOUNT - The QD has audible ratcheting adjustment for tight, consistent installation, and can easily be removed or installed using the large lever and release. UNBEATABLE VALUE - The DELTA is a versatile, durable magnifier that can be paired with any red dot sight, and it's backed by a Transferable Lifetime Warranty.
