I’m having fun with the magazine loaded 590 but wish the tube was longer for a bayonet lug. Is there any tube extensions with a lug on it I could get online anywhere? thanks
If you want to spend that much money, S&J Hardware has one. They are for an 870 though, but if you know the diameter of the 590's heavy barrel, one of these might fit. NCstar makes one for the 500 which might fit if its 2 pieces.
I tried the clamp-on ones and couldnt make it work with my 590M. I'm actually in the middle of designing a prototype one for my 590M (it requires making a slight modification to the bayonet hilt to make it fit).
I'm looking at rolling out a product kit in the next couple of weeks if there is enough interest.
