Patternmaster 12ga Shooting Sport Series SKEET (0.730”) has our patented “Gas over Constriction Technology” utilizing a “Coil Zone” which is made up of a channel inside the tube used to harness gas expelled from the ammunition. “Coil Zone” channels are spun in a negative twist to stabilize for even, consistent patterns and keep the tube tight in the barrel. Anaconda SKEET will throw a skeet pattern with distances out to 27 yards. SKEET tubes extend out the end of your barrel about one-quarter of an inch. The extension is diamond knurl to allow for hand tightening and efficient tube change. Tubes available in SILVER color only.
