Remington Choke Thread Tool

Picked up a Remington 870 28" 12 gauge barrel the other day that had a choke seized up due to rust / corrosion. I finally broke it free and have had it soaking in penetrant, but I'm looking for a good way to chase the threads.

My Benelli has a tool on the choke wrench to chase threads, but it's a different thread pitch.

Does anyone know of a tool that will work with the Remington choke system?

I would suggest reading the comments on this thread for some guidance.

Thanks Dan... good reading.

The threads on this barrel are not damaged, but I'd like to run something through (besides a choke) that can chase (w/o removing metal like a finishing tap)the build up off the threads.

I may have to get an oversize brass brush and run it through on a drill to clean the threads. Anyone tried this?

Ran across a thread that mentioned a 50/50 mix of diesel fuel and acetone being best for soaking threads before hitting them with a wire brush.

Well... I've got both of those. I'll give it a try.

I don't know what affect it would have on the bluing, but you could blast it out with some brake cleaner real good then wipe it out. I would lube the threads and just thread it in and out a few times slow and put some antisize on it when you put it back in.

Lots of soaking and a Remington Choke Tube Wrench (the one that allows for 3/8 inch ratchet to be inserted) did the trick. It allowed for a smooth consistent torque to break free.
