I bit the bullet and broke the bank for a new scope mount. I'm so impressed with it I thought I needed to show it off a little. First of all SWFA did an excellent job of packing it and even same day shipping. This price was $282 out the door with the optional forward rail added. The base model is about $250. This Manufacturer makes other mounts, for about everything else as well. However this one is made just for the AR-10's and 15's. As seen in the photos of how it attaches to the upper rail. My barrel is on back order with WOA so no range report any time soon. Enjoy the pictures.
