Rhino Shooting Sports has collaborated with Brandon Powell of Powell Performance Shooting to come up with an out of this world new chokes tube series to help you "Shoot like an Alien". This is the first time Rhino has come out with a choke tube that is not ported. The unique coating on the outside is individual to each choke tube and distinguishes these chokes from every other manufacturer on the market. They hit harder than anything out there, making them out of this world!
