Get the right wrench for the tubes you use. There are several different types of choke tube wrenches to use with Browning choke tubes. This one is designed for use with Standard Invector choke tubes only. Please note that Standard Invector, Invector-Plus and Invector-DS have different choke designs and it is important to select the correct wrench for removing and reinstalling your shotgun's choke tubes. Many extended tubes are easy to remove with fingers, but most gauged choke tubes have wrench slots hidden inside that only accept the correct wrench for that gauge.

Flat wrench design. The flat wrench design has slots to fit different gauges of Standard Invector choke tubes. This is very handy just to have around in your shooting bag or on your keychain. Plus, it has a handy screwdriver bit on the end. This version is for Standard Invector flush-mounted tubes.

To avoid damaging the top of a tube, it is not recommended for use with extended choke tubes. If you need to use it in a tight spot, proceed very, very carefully.
