I made my purchase at Freedom Gorilla because of their excellent customer service / support. FGs CSRs were patient, informative, and helpful. FG will be my first stop for future optic purchases.
I purchased the H507C Green for my Springfield Echelon. It’s performing exactly as advertised. I’m very satisfied with its range performance. I’ll probably buy another one for another pistol.
Bottom line, zero malfunctions, zero issues, zero concerns.
