Machined from \u003cstrong\u003estainless steel\u003c\/strong\u003e and finished in \u003cstrong\u003echrome\u003c\/strong\u003e, this tube is purpose-built to control the spray pattern and deliver consistent shot strings at the range or in the field.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eInvector-DS stands for \u003cstrong\u003eDouble Seal\u003c\/strong\u003e, Browning's design that adds a secondary seal ring near the muzzle in addition to the standard choke threads. The double-seal interface keeps gas and fouling out from behind the tube and helps the threads stay cleaner between cleaning cycles, so the tube seats securely and consistently shot after shot. Invector-DS tubes are also noticeably \u003cstrong\u003elonger\u003c\/strong\u003e than standard Browning choke tubes, with extended tapers that Browning optimizes to specific pattern percentages rather than to dimension alone.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThis tube is a \u003cstrong\u003eModified\u003c\/strong\u003e constriction with a \u003cstrong\u003e.020 inch\u003c\/strong\u003e bore taper, designed to put roughly \u003cstrong\u003e45-55%\u003c\/strong\u003e of the pellets in the pattern at \u003cstrong\u003e40 yards\u003c\/strong\u003e. It is recommended for use out to about \u003cstrong\u003e45 yards\u003c\/strong\u003e, making it a versatile general-purpose choke tube. The \u003cstrong\u003eflush\u003c\/strong\u003e mount keeps the tube seated inside the bore so it does not protrude past the muzzle, preserving a clean barrel profile.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eThe choke is approved for use with \u003cstrong\u003esteel\u003c\/strong\u003e, \u003cstrong\u003elead\u003c\/strong\u003e, and \u003cstrong\u003enon-toxic\u003c\/strong\u003e shot, so it works with modern non-lead loads as well as traditional lead or steel shot. The construction is \u003cstrong\u003enon-ported\u003c\/strong\u003e for a straight-through pattern without side venting, and the polished \u003cstrong\u003echrome\u003c\/strong\u003e finish on the \u003cstrong\u003estainless steel\u003c\/strong\u003e body resists corrosion from shot residue and weather exposure.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"font-size: 14pt;\"\u003eInvector-DS tubes only fit Browning shotguns specifically marked Invector-DS on the barrel(s); they are not interchangeable with Browning Standard Invector or Invector Plus choke systems.
