I have found that you Always need a wrench even if you have those extended chokes. The chokes always get too tight.
I have a "Royal" choke wrench for my remchokes I bought at a local range on L I. It was made in a local shop by one of the local shooters and is quite ingenious, having an expanding rubber sleeve that compresses inside the choke tube. Can't find the guy who made them and the range has been closed down with NIMBYitis. Best wrench I have ever used.
I have all my chokes in a plastic MTM shell box designed to hold 25 12 ga shells. I keep the wrench in the box with all my chokes. Keep it in my shooting bag.
