About 4 years ago I purchase a jellyhead inv. 12ga .660 choke for what was suppose to be for a super x2.I no longer have the gun but if I recall the choke didnt even fit the gun.yes I know I should have dealt with it then. I recently came across this choke in a box of junk I had and want to figure out what gun iit belongs to so I can sell it. With no numbers on the choke is there any way to identify wat gun it will fit?
