Holosun HS507K-X2 Reflex Red Dot Sight, Black Anodized

Holosun HS507K-X2 Reflex Sight — Compact pistol reflex sight. The HS507K-X2 is a non-magnified reflex optic designed for subcompact and concealed-carry pistols to provide a simple, fast aiming reference.

This sight addresses the need for a small, durable pistol optic with quick target acquisition and minimal footprint. It is intended for subcompact carry pistols (the product is noted as a direct fit for certain models such as the P365X/XL and may require adapter plates for slides with a four-boss interface). The design emphasizes low weight, a compact viewing window, and features that reduce inadvertent setting changes during carry.
