Yes, this should work with that.
No it will not work on a 20 gauge. I bought it based of the expert's answer and found out he obviously doesn't know what he is talking about.
The Leapers UTG Universal Shotgun Forend Wrench is not a choke tube wrench and is only compatible with the shotguns listed. The choke tube wrench at the link below will work for a 12 gauge.

Yes. The Leapers UTG Universal Shotgun Forend Wrench is compatible with the Remington 870, Mossberg 500, 835, and Other Similar Variants such as the 590.
Yes it will be a good tool for adding Stream/lights TL-Recker on both Remington and Mossberg
twelve gage models . Investment cast will be heaver catching the process's name . Little if any force
will be needed in use with a brass rap on the collet getting it broke loose . Good Luck
