The Browning Standard Invector 12 gauge X-Full Turkey Special choke tube is designed to offer even tighter patterns than capable with a Standard Invector Full constriction choke. It does this with a moderate choke tube extension (about 1/3 longer than a flush fit tube) and an improved internal taper.
12 gauge Standard Invector was one of the original removable choke tube designs. Standard Invector shotguns have conventional bore diameters and are not back-bored as many Browning shotguns are today. The original, shorter, flush fit tubes were supplied on large numbers of Browning shotguns, and they still offer great performance for most hunting and target situations. The Standard Invector X-Full Turkey Special extended choke tube has more specialized patterning capabilities for shooting at longer ranges.
Standard Invector tubes fit only Browning shotguns designed for Standard Invector and are not for use in shotguns showing Invector-Plus or Invector-DS on the barrel(s).
Do not use X-Full Turkey Special, X-Full Turkey/Trap Special, or Full constriction choke tubes with steel shot. Using an over-tight choke constriction with steel shot will result in an ineffective “blown” shot pattern.
X-Full choke tubes extend beyond the muzzle, have a knurled end, and are ported.
