I am using 4 -60 screws, and one-side mount. will see how that mount hold. BTW, 510c is lighter than cmore slideride, many shooters use one side mount for cmore, right?
yes, I compared to dpp 2,5moa, R3 3moa and 8moa RTS2. For brightness, 510C is similar to R3 3moa and RTS2, a little brighter than my DPP . But dot is kind of small, wish they will produce a 6moa or 8moa reddot with the huge window
