Early in the history of Standard Invector choke tubes, it became apparent that a version was needed that would deliver a tighter pattern overall with lead loads, specifically tight patterns at 40 yards, producing greater core densities. At the time, tight, dense patterns were proving to be extremely effective for delivering the necessary pellet hits in the neck and head necessary to drop a large tom instantly. This choke tube was the answer. Over the years, this tube has gained a strong reputation with serious turkey shooters. The bottom line is that an extended tube is essential if you are presented with longer shots and are using a Standard Invector shotgun.
With its extended length, tight choke constriction, and longer precision taper, this choke tube differs from other 12 gauge Standard Invector tubes. It functions best when used with quality turkey ammunition and offers tight patterns using lead Turkey loads including copper plated, blended shot, resin-type and non-toxic (non-steel) loads.
The extension doubles the length of the tube itself. It has been designed to produce tight, consistent patterns. Clay target shooters have also found that this tube produces excellent patterns with lead shot at handicap distances.
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.
