Now you can have the Benelli M4 look the way it was intended. I’m in the final stages of finishing this project up, I should have 19-20 of these available for purchase initially. They are made from 4130 steel with a manganese phosphate finish. It expands the m4 capacity to 5 x 3”, and 6 x 2.75”.
I’ll be posting more info and pics as I have them. Thanks!
