Vortex Defender XL by Bob, Verified Owner, January 26, 2025

Better than Holosun 507Comp by m0b00st, Verified Owner, February 18, 2025
I prefer this to my 507comp for multiple reasons. The window is taller, the glass is just as clear, the dot is more crisp, the buttons are easier to use, the battery tray is far superior. Don’t hesitate to try this dot if you’re on the fence.

Vortex Defender XL by Ghost, Verified Owner, March 3, 2025

The rush of competitive shooting may bring us all together. But when you want an optic that sets you apart, depend on the Defender-XL. Target to target. Stage to stage.
