Patternmaster 12ga Shooting Sport Series (SSS) TRAP LONG (0.700”) 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. TRAP LONG will throw an IMPROVED MODIFIED pattern with distances out to 60 yards. TRAP LONG tubes extend out the end of your barrel one inch. The extension is diamond knurled to allow for hand tightening and efficient tube change. It is also marked with two parallel lines through knurling for easy identification. Tubes available in SILVER color only.
