Replacement and additional tubes and wrenches are available from
your Browning dealer, or by contacting the Browning Consumer
Department. See the inside of the front cover for contact information.
CHOKE TUBE SELECTION
To help you choose the correct choke tube for each hunting and
shooting situation, all Browning Invector choke tubes are inscribed
on the side with the patterns they produce with both lead and steel
shot. Each Invector tube also has notches in the top rim of the tube
(Figure 12). These notches are a code to allow you to determine the
choke designation while the tube is installed. Rim notches refer
specifically to lead shot. You will need to use the charts on the next
page to cross-reference from lead to steel, and determine the
appropriate tubes for your ammunition and hunting/shooting situation.
Several choke tubes are supplied with your shotgun. The choke tubes
listed are also available as accessories. Remember, Standard Invector
and Invector-Plus tubes are not interchangeable. Invector-Plus tubes
are for Browning shotguns with back-bored barrels only. Before
removing or installing tubes, or reading the rim notch code, make
sure your shotgun is completely unloaded and the “safety” is in the
on safe position.
CHOKE TUBE REMOVAL
1 Place the “safety” in the on safe position. Always make sure the
shotgun is completely unloaded. Always keep the muzzles pointed
in a safe direction.
2 Use the choke tube wrench to loosen the tube, turning it
counterclockwise. Finger-twist the tube the rest of the way out
of the barrel.

All current production 12 and 20 gauge Cynergy shotgun barrels
have been threaded to accept the Invector-Plus
™
choke system.
28 gauge and .410 bore Cynergy shotgun barrels have been threaded
to accept the Standard Invector
™
choke system. Standard Invector and
Invector-Plus tubes are not interchangeable. You may confirm the
choke system of your shotgun by looking on the right side of the
barrel where the specifications are inscribed, where the choke
markings are normally located.
The constriction of each choke tube is indicated twice on the choke
tube: on the side of the tube, and indicated with a “notch” code on the
top rim of the tube. The included universal choke tube wrench is used
to remove and install choke tubes.
Invector and Invector-Plus choke tubes are compatible with factory
ammunition that has been loaded in compliance with SAAMI
specifications, including magnum lead and steel shot loads, sabots
and shotgun slug loads.
