Product Details
This adapter lets you mount a Holosun 509 optic onto your Picatinny rail in the lower 1/3 position, which gives you a comfortable sight picture without having to crane your neck. It's made for the standard Picatinny setup and works with the 509MNT-1.63-PIC footprint. If you're upgrading an existing rifle or building one from scratch, this is a straightforward piece that gets the job done.
