The Franklin Armory® Picatinny Tripod Adapter is designed to attach any rifle with a picatinny rail to a commercial tripod. The PTA was specifically designed to mount the CSW to commercial tripod applications. The PTA works with tripods threaded in the most common commercial thread pitch, both 1/4-20 and 3/8-16. It also has an index hole to keep the mount from rotating. Franklin Armory® stocks Smith Victor tripods that work well for this application. By using a good rifle with a rail, a PTA, a solid tripod, and a folding chair, it is very easy to set up a rock solid shooting position in the field for varmint hunting or target shooting.
