Standard Invector Choke Tubes

Standard Invector Choke Tubes. The original Browning removable choke tube system. 

Invector Barrel Stamp
On many shotguns, look for a barrel stamp that says "Invector" or "Standard Invector" like the one pictured above.
 
  • These fit only shotguns marked Invector or Standard Invector.
  • They never fit shotguns marked Invector Plus (+) or Invector-DS.
  • 10, 16 and 28 gauge and .410 bore Browning shotguns usually utilize the Standard Invector system. 

  • The Standard Invector interchangeable choke tube system offers consistent, dense shot patterns with the right constriction needed for the shooting situation.
  • Threads on the breech end of the choke tube help prevent gases from slipping between the choke tube and barrel that could damage the choke tube and the barrel.
  • Standard Invector is standard on 10, 16 and 28 gauge, and .410 bore Citori 725, Citori, Cynergy, and Gold models.

STANDARD INVECTOR, INVECTOR-PLUS AND INVECTOR-DS ARE NOT INTERCHANGEABLE. Make sure you know the system that fits your shotgun before proceeding.  For advice on choosing a choke tube appropriate for your shotgun READ MORE HERE.
