INVECTOR CHOKE TUBE CODE—
To identify individual Invector tubes, refer to
the abbreviated indications on the side of the
tube, or use the identification mark(s) located
on the top rim of each tube. (See Figure 14).
INVECTOR TUBE SELECTION
To help you choose the correct choke tube for
each hunting 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. These notches are a code to
allow you to determine the choke designation
while the tube is installed. Rim notches refer spe-
cifically to lead shot. you will need to use the
chart below to cross-reference from lead to steel,
and determine the appropriate tubes for your am-
munition and hunting/shooting situation.
Several tubes are supplied with your Browning
shotgun. The tubes listed are also available as ac-
cessories. Remember, Standard Invector and
Invector-Plus tubes are not interchangeable.
Invector-Plus tubes are for Browning guns with
back-bored barrels, such as your new Auto-5.
Older Auto-5 shotguns are Standard Invector. Be-
