Night Fision Holosun K Optic Plate + Backup Sight Combo Features The Night Fision Optic Plate + Backup Sight Combo is built specifically for Springfield Hellcat models offering compatibility with the Holosun 507K and other optics that share its mounting footprint. Crafted from premium 17-4 stainless steel and machined to tight tolerances this plate is engineered to withstand the recoil forces of regular firing without loosening over time. A nitride coating adds additional protection against corrosion and wear extending the plate s service life under hard use. This combination of material choice and precision machining ensures the mounted optic stays secure and properly indexed shot after shot. The combo includes Night Fision s premium black sights designed to co-witness with the mounted optic so shooters retain a reliable backup aiming reference if the red dot fails or the battery dies. Each package also comes with extra screws and an installation tool making setup straightforward without needing to source additional hardware. This bundled approach saves Hellcat owners the effort of buying a plate and sights as two separate purchases streamlining the path to a fully optic-ready carry pistol. The Night Fision Optic Plate + Backup Sight Combo is a solid well-engineered choice for Springfield Hellcat owners running a Holosun 507K optic.
