Tight, Consistent Patterns, Less Shot Deformation
Longer parallel section than Carlson's conventional tubes gives consistent shot patterns. Extra smooth interior surface minimizes shot deformation. Laser marked constriction provides fast identification. External knurled ring extends approximately 3/4" from end of barrel for fast changes between stations. Can be used with steel shot.
