Has anyone tried the Blackout choke Bass Pro is selling? I think it is made by Carltons. I picked one up in .575 ported for my sons 20ga Mossberg.
I have a Carlson .575 choke for my 870, if they are made by Carlson, they should be some good chokes
I've got one for my 870 20ga but it didnt do well with the Federals I shoot. I used Magnum blend with the Blackout choke and the Heavyweights had a better pattern
I also have the Blackout choke for my Benelli 12ga and it patterned really well. Even better than my Kicks choke.
All and all, its a good choke for the money
