Primary Arms Optics PLx Top Cap Reflex Mount - 30mm

The Primary Arms PLx Top Cap Reflex Mount is an optic-mount accessory designed to replace the top ring cap of Primary Arms PLx 30mm scope mounts, creating a clean, low-profile perch for an offset reflex sight or red dot. It's an efficient way to add a fast-acquisition close-range optic directly over an LPVO without introducing a separate rail or clamp-on mount, and it is cut for the popular RMR / 507C footprint.

Machined from 7075 aluminum and finished in a black hardcoat anodized coating for corrosion and wear resistance, this top cap is purpose-built to integrate with the upper ring of a 30mm PLx scope mount. When installed, the base of the mounted reflex optic sits at 2.04 inches above the rail, giving shooters a consistent co-witness height with the host scope.

Designed for shooters running a variable-power scope who want a dedicated close-quarters backup dot without adding bulk, length, or weight to the front of their rifle, this PLx top cap reflex mount delivers the same rugged build quality expected of the Primary Arms PLx line.
