870 20 inch mag extension

[Carter124]

Just wondering if anyone knows of a +3 extension that will sit flush with my 20 inch barrel on my 870.

Thanks,

Carter

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.

That's exactly what I'm looking for, can you tell me where you bought yours? How is the quality, any feeding issues? Also is the clamp included or was it a separate purchase?

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.
