Patternmaster 12ga Browning Invector Ds Clas
Patternmaster's Classic MID RANGE tubes will extend out the end of your barrel about 5/8 of an inch and has an effective range out to 50 yards. You will see a pattern similar to a Modified constriction choke on paper, but because of the patented "stud ring" inside the tube, there is a much shorter shot string. This shorter shot string will allow more shot on target all at once so your down range energy is sure to kill instead of cripple. Our MID RANGE tube can be used with steel or other non-toxic ammunition as well as lead, and also with 2 ¾" or 3" or 3 ½" shells. MID RANGE tubes only come in Black and are not ported. Pick your favorite shot size to use which can range from 8 to BB Non-Toxic/Steel and Lead 8 to 000 Buck. Patternmaster tubes are made with Carpenter Custom 630 (aircraft quality) 17-4ph stainless steel and are heat treated to the optimum level for best performance.
