46 CHROME-PLATED CHAMBER AND BORE are critical for today’s steel and Hi-Density (HD) shot. Hard chrome makes the surfaces highly resistant to wear and gives you superior protection from rust and corrosion. That’s why all smoothbore Super X® Pump shotguns feature a hard-chromed chamber and bore. SPEED-PLUG SYSTEM makes it easy to remove the three-shot adaptor. Just remove the magazine cap, push on the spring retainer holding the spring in place, twist and remove the adaptor. This trouble-free design that lets the shooter “pull the plug” in mere seconds without tools. BACK-BORED TECHNOLOGY is based on extensive research and testing to find the secret to tighter, more consistent patterns. Instead of the traditional bore size of .729", this research shows the ideal 12 gauge interior diameter is .742". In 20 gauge barrels the ideal bore diameter is .630" instead of the standard .618". If the bore is any larger the gases will blow by the shot cup and reduce pellet velocity. If the bore is too tight the pellets are deformed as they pass through the forcing cone, causing poor ballistic performance. From the duck blind to the firing line, the INVECTOR-PLUS™ CHOKE TUBE SYSTEM is the world’s most consistent. The Super X® Pump comes with full, modified and improved cylinder flush-mounted choke tubes so the gun is ready for anything, right out of the box.
