Product Details
This adapter lets you mount a Holosun 507C red dot sight onto a gun that has the newer 509 footprint - basically, it's the bridge that makes an older optic work with a newer gun. If you've already got a 507C you love and just picked up a pistol with the 509 mounting pattern, this saves you from buying a whole new sight. It comes in black and installs straightforward. It's a practical solution for folks building out multiple guns without breaking the bank on duplicate optics.
