870 20 inch mag extension

From my research any +3 mag extension will sit flush with a 20 inch barrel. Personally I would choose one with a barrel attachment, +3 mag extensions seem to me to be a little long to be unsupported. Also I have been waiting on S&J hardware to be getting in more Remington Factory +3 Police extensions.
 
I too was waiting for the factory extensions to be in stock again until I seem this:

Does anyone know if the s&j sits flush or will extend past the barrel? It looks like it has the same nub as the factory extensions
 
I have a Choate +3 extension on my 870 with a 20" barrel. I Concur that a clamp should be used.

I got the extension complete with clamp and follower from Brownells. I have not had any issues with it. Construction consists of a steel tube with a plastic end-cap crimped in place.
