Holosun Picatinny Rail Adaptor for the 507C/508T
The Holosun Picatinny Rail Adapter for the 507C / 508T is a simple mount that lets you run those pistol optics on a rifle, PCC, or shotgun with a standard Picatinny rail. It basically turns your 507C or 508T into a versatile rifle-ready red dot without needing a dedicated slide cut or pistol mount. The adapter is low-profile, solid, and keeps the optic stable so you can maintain a consistent zero even under recoil. It’s a clean, no-drama way to expand what your optic can do across different platforms.
