I have an M4 and it came with the internal choke with three (3) notches, I assume that it is a three. My understanding is that to shoot slugs, I must use a four or five, is that correct???
Where can I buy the appropriate Benelli choke to be able to shoot slugs??? Can you be specific as to what I need please for all you Benelli M4 experts.
Thanks for any help guys!
