The KPLT-507C adapter allows Holosun 407K and 507K red dot sights to be installed on pistols with slides cut for the RMR footprint. The dedicated adapter provides a precise transition from the narrower K Series footprint to the wider RMR mounting interface.

Compact Design and Low Profile

The plate features a low-profile design that keeps the optic's optical axis as close to the slide as possible. This configuration makes it easier to align the aiming point with the pistol's iron sights while maintaining a natural shooting position.

Durability and Precision Fit

Made from high-quality aluminum, the adapter provides excellent rigidity and resistance to the shock generated during slide cycling. Precision-machined contact surfaces ensure a secure, play-free installation, which is essential for repeatable accuracy and reliable zero retention under field conditions.

The precisely matched footprint minimizes the risk of the red dot sight shifting under recoil. The lightweight aluminum construction weighs only 30 g, adding minimal weight to the slide while maintaining resistance to external conditions.
