Steel Shot Tubes; Slim Profile Fits Doubles & Over/Unders
Reduced diameter, extended, knurled ring, gives the necessary
clearance to let you use two choke tubes in side-by-side and
over/under guns. Extended tube places the choke restriction
outside the barrel. Prevents steel shot battering from jamming
tube into the barrel. Not for use with "F" or "T" size shot. Knurled
ring for easy removal without a wrench.
