T Inman;
Good afternoon once again sir.
The one I have - I think and will go double check now - is this one.
https://www.sjhardware.com/product/powerfeed-no-jam-combat-shotgun-follower-type-1-hivis-green/They sold it as a universal fit and I want to say I've installed one of these on a Remington 870 without issue.
All the best to you once again and we'll be in touch.
Dwayne
