What size mag extension for a 20" 870?

[Empir3]

The title is pretty clear, I am looking to find out what size/length of magazine extension I need for a 20" barrel on an 870 so that it is flush at the muzzle.

Also, where might be a good place to purchase one of these from?

Thank you for your input.

Cheers,

Derek

You need to look for a 3 shot extension, these fit flush with a 20in.

A 2 shot extension fits flush with an 18.5 in barrel.
