C&H Precision FN 509® V4 MIL / LEO إلى Trijicon RMR / SRO / Holosun 407C / 507C / 508C / 508T

Finally, an optic mount that doesn't need a gunsmith to install—torqued it down in five minutes and the screws didn't strip. The machining is so precise that my 507C sits absolutely flush with the slide, no shims needed.

The machining on this plate is incredibly tight—it seats onto the slide with zero wobble, and the screw holes lined up perfectly for my RMR. Shipping from the Georgia shop was quick, and you can tell it’s a quality piece from a family operation.

The fit on my FN 509 is absolutely perfect—the plate dropped right into place with zero wiggle, and the provided screws were the exact right length for my Holosun.
