Helpful Positive Review Vortex Defender XL by Bob, Verified Owner, January 26, 2025

Helpful Positive Review Better than Holosun 507Comp by m0b00st, Verified Owner, February 18, 2025

Helpful Positive Review Vortex Defender XL by Ghost, Verified Owner, March 3, 2025

Helpful Positive Review Best PCC competition sight ever by GMS, Verified Owner, July 3, 2024
If you run a PCC in competition, this optic is what you want. I have been running PCCs with C-More, Trijicon MRO, and a Vortex UH-1 over the years. This optic trumps them all. The window is slightly larger than a C-More. I absolutely love the aut...
