I’m going to change the forend on my new Mossberg 590A1. It has a “tactical” style on it now, with slots for M-Lok accessories. I’m swapping it out for a traditional corncob style. I have zero interest in attaching gizmos to my shotgun.

I used to have one of those tools to remove the locking ring, the ones that are essentially a piece of tubing with nubs on the end. That was over 30 years ago, and it has gone the way of the dodo.

Any suggestions for a substitute tool? Or should I pop for another piece of tubing that will sit unused for a millennium thereafter?

I’ve convinced myself I can simply chase the locking ring with a piece of brass rod, tap tap-tapping it around.

Edited to add that I can duplicate the correct tool using a piece of PVC, but I can’t recall how firmly those locking rings are cinched down.

I would think you could make it work without the specific tool. Maybe a small punch and hammer to break it free then a thin screwdriver to push it around. I would think thinner pipe like conduit would work better but Most folk don’t have scraps of 1” or 1-1/2” conduit laying around (the bonus of working construction is you can pick up a lot of odd stuff!). You might get something like a 1” conduit coupling you could cut and file on to fit. Maybe a pair of larger snap ring pliers of you have a set? Would your former gun shop have something like that you could go in a borrow?
