The standardized mounting interface shared by the Holosun line of optics with the Leupold DeltaPoint Pro is commonly referenced by a specific term. This mounting pattern allows compatible red dot sights to be securely attached to various firearms, slides, or mounting plates designed to accommodate this particular configuration. For example, a pistol slide milled to accept optics conforming to this standard can directly mount both a Leupold DeltaPoint Pro and certain Holosun models without requiring adapter plates.
Adherence to this standard provides benefits such as increased versatility in optic selection and simplified installation processes. The prevalence of this mounting standard has led to its widespread adoption by firearm manufacturers and aftermarket parts suppliers, ensuring a broad range of compatible products. Its existence allows users to change between compatible optics with minimal modification. This intercompatibility has contributed to the popularity of both the Leupold DeltaPoint Pro and the Holosun optics that share this mounting pattern.
