[Slimshady]

anyone know if any mag tube cap/extension threads are interchangeable within the various popular brands?
(Rem870/1100, Moss590/930, Win1200/1300, benneli, the various turkish brands, etc.)

gotta be one or two...

Benelli will fit a Fabarm. Not sure if that's popular or not.

If you go to the Nordic Components web site and look at the coupling nuts, they specify what each nut will fit. Sorry no Turkey guns are listed.
