I'm looking to upgrade my choke tube for the Mossberg 500. I currently have the primos original jelly head choke tube .660. I currently run the long beard XR, and would upgrade to the tss down the road. I already got two, one was Jebbs chokes and Indian creek not sure what makes them difference is between other then the look of the porting. Thanks in advance for any help I know really little about choke tubes.
