Midas Grade choke tubes use the long taper technology of Invector-Plus, but produce tighter patterns. It extends beyond the barrel for easy removal and installation, no wrench necessary. It uses minimum gap geometry plus a high resolution "RMS" finish to reduce buildup of plastics in the shotgun bore. These tubes are stainless steel with a black oxide finish and a laser-etched gold accent band. Invector-Plus choke tubes fit only Browning shotguns designed for Invector-Plus and are NOT for use in shotguns showing Standard Invector or Invector-DS on the barrel(s).
