Product description
Sometimes Smaller is Better
This adapter plate allows you to mount the compact Holosun 407K/507K red dot sights onto firearm slides originally milled for the larger Holosun 507C and Trijicon RMR footprint. The Holosun 507C to 407K/507K Optic Plate Adapter allows you to customize your firearm with a more compact optic while maintaining secure and reliable mounting.
Seamless Compatibility
Converts the Holosun 507C and Trijicon RMR footprint to fit the compact 407K/507K series optics and other optics using that footprint like the AT3 ARO Mini. This enables users to mount their preferred micro red dot to their firearm.
Strong and Secure Adapter
The plate and screws are made from high-strength steel to avoid issues such as bending, warping, or breaking that other adapter plates that use weaker metal can have. Additionally, this adapter plate has been tested to withstand rigorous use and heavy recoil, ensuring your optic stays secure and zeroed.
Low-Profile Design
Maintains a thin profile, minimizing added bulk and providing a good fit with your optic without raising your optic to skyscraper height.
Easy Installation
Includes all necessary hardware and torx allen key for quick and straightforward installation, making it easy to confidently and quickly upgrade your setup. We would still recommend using a torque wrench to get exact poundage but tightening it until it’s tight will do also.
Precision Fit
Engineered to exact specifications, the adapter plate ensures a tight and stable connection between your optic and slide, preserving zero and delivering consistent performance.
