Invector Interchangeable Choke System

All current Auto-5 shotguns have barrels that are threaded to accept the Browning Invector-Plus Interchangeable Choke System. You may confirm this by glancing on the right side of your barrel where the specifications are inscribed, and where the choke markings are normally located. All older Auto-5 models and the Auto-5 Buck Special are conventionally choked. The word, INVECTOR denotes that the barrel is threaded. The degree of choke tube is indicated twice on each choke tube: Inscribed on the side of the tube, and indicated with a "notch" code on the top rim of the tube. Invector Choke Tubes are made with tempered steel and are fully compatible with all FACTORY AMMUNITION (loaded in compliance with SAAMI specifications) including Magnum lead and steel shot loads and rilled slug loads.

DO NOT FIRE THIS SHOTGUN WITHOUT HAVING AN INVECTOR CHOKE TUBE INSTALLED.

Permanent damage may result to the threads.

DO NOT USE BROWNING INVECTOR CHOKE TUBES IN ANY SHOTGUN BARRELS NOT SUPPLIED BY BROWNING. ALSO, DO NOT USE ANY OTHER CHOKING DEVICE IN ANY SHOT-

TUBE REMOVAL—

2 Open the action, locking it rearward, and place the "safety'' in the "on safe" position.

3 Use the Invector wrench to loosen the tube, turning it counterclockwise. Finger twist the tube the rest of the way out of the barrel.

TUBE INSTALLATION—

1 UNLOAD YOUR A-5 FULL Y. INSPECT THE CHAMBER, FEED MECHANISM AND MAGAZINE TO MAKE THEY DO NOT CONTAIN ANY SHELLS.

2 Open the action and place the "safety" in the "on safe" position.

3 Before installing a tube, check the internal choke tube threads in the muzzle, as well as the threads on the Invector choke tube to be sure they are clean. Lightly oil the threads with an oil like Browning Oil.

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 011 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 specifically 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 ammunition and hunting/shooting situation.

Several tubes are supplied with your Browning shotgun. The tubes listed are also available as accessories. 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 models

are Standard Invector. Before removing/installing tubes, or reading the rim notch code, make sure your shotgun is fully unloaded.
