Bought this at SM Gun Shop in Eugene, OR... didn't realize they have a "no returns no exceptions policy". So I'm taking a $5 loss at this price. This was the wrong rail for my application, it was meant for an actual scope not a dot sight with integrated mounts. So it's unused and ready to go on a Browning Buckmark .22 lr pistol. Takes Weaver style rings. Weigland Combat Handguns brand, part no. BBM22S.
