I have two like new La Rue Picatinny Risers for Sale.
Both were purchased new from La Rue, and briefly mounted on rifles before I decided I didn't like the setups I had. Both have been coated with DuraCoat matte black.
Asking $75.00 each shipped. If you're looking for a La Rue riser, here's a great way to save $50.00.
