TOTAL BARREL DYNAMICS Total Barrel Dynamics is the combination of Vector Pro forcing cone lengthening, Back-Bored Technology and an Invector interchangeable choke tube system working in unison to optimize shot pattern performance. Each component of Total Barrel Dynamics plays a part to reduce shot deformation and keep patterns dense, putting more pellets on the target. To ignore any single aspect of the system weakens the overall performance. Total Barrel Dynamics is featured on A5, BT-99 and on 12 and 20 gauge Citori 725, Citori and Cynergy models. VECTOR PRO LENGTHENED FORCING CONE • The forcing cone is the tapered transition between the chamber and the bore that constricts the shot column. The longer the forcing cone is, the more gradual the constriction. Vector Pro is better than our competitors’ forcing cone designs because it has a more gradual constriction. • The Vector Pro forcing cone reduces stress on the shot column as it moves into the bore, reducing pellet deformation for more uniform patterns and more pellets in the center of the pattern. • Lengthening forcing cones is a popular and expensive aftermarket practice done to increase shot pattern performance but it comes standard on A5, BT-99 and on 12 and 20 gauge Citori 725, Citori and Cynergy models. BACK-BORED TECHNOLOGY • Back-boring enlarges the bore to the maximum diameter to increase shot velocity and minimize pellet deformity for more uniform patterns and a reduction in felt recoil. • Extensive testing has shown that Back-Bored Technology reduces the friction between the shot cup and the bore, but does not allow gases to slip past the shot cup that would result in reduced pellet velocity and blown patterns. • Back-Bored Technology specifications minimize shot deformation and maximize pattern uniformity, consistency and density. Back-Bored Technology is standard on A5, Maxus II, BT-99 and on 12 and 20 gauge Citori 725, Citori, Cynergy, BPS and Silver models. INVECTOR-DS CHOKE TUBE SYSTEM • “DS” stands for double-seal, our proprietary differential-banded brass seal. It compresses against the barrel wall to keep the choke tube threads clean and makes installation and removal easier than any other muzzle thread system. • Invector-DS choke tubes combine muzzle-end threads and thin-wall construction for a longer, more gradually tapered choke tube that produces extremely consistent, dense shot patterns. • From Cylinder to Extra Full, Invector-DS shot patterns tighten consistently in reliable, evenly scaled steps. • Muzzle-end threads minimize the flare at the end of the barrel for improved shotgun appearance. A slightly lighter overall barrel weight is achieved for a faster swing and improved balance. • The more gradual taper of Invector-DS choke tubes reduces shot deformation for fewer flyers and gaps in the pattern and allows higher shot velocities for hard-hitting performance. • Invector-DS is standard on A5 and Citori 725 models. • View the full line of Invector-DS choke tubes on pages 151, 153 and 154. INVECTOR-PLUS CHOKE TUBE SYSTEM • Invector-Plus started the long choke tube revolution. An ever-growing collection of world, national and local championships is proof of its patterning performance. • The Invector-Plus choke tube system works with Vector Pro and Back- Bored Technology to offer consistent, dense shot patterns with the constriction needed depending on the shooting situation. • The long choke taper inside an Invector-Plus choke tube produces consistent patterns with more uniform densities and fewer flyers. • Threads on the breech end of the choke tube help prevent gases from slipping between the choke tube and barrel that could damage the choke tube and the barrel. • Invector-Plus is standard on 12 and 20 gauge Maxus II, Citori, Cynergy, Silver, BPS and BT-99 models. • View the full line of Invector-Plus choke tubes on pages 151 through 154. STANDARD INVECTOR CHOKE TUBE SYSTEM • The Standard Invector interchangeable choke tube system offers consistent, dense shot patterns with the right constriction needed for the shooting situation. • Threads on the breech end of the choke tube help prevent gases from slipping between the choke tube and barrel that could damage the choke tube and the barrel. • Standard Invector is standard on 10, 16 and 28 gauge, and .410 bore Citori 725, Citori, Cynergy, and Gold models. • See pages 151 through 154 for our complete line of choke tubes.
