CG16, I'm afraid I can't help you...but have favor to ask. I've heard the M12 Heavy Duck had a shorter LOP...around 13 5/8. Could you confirm that for me, and if it is 13 5/8, let me know if you think it is about right with a duck hunting coat on, or a little short. Thinking of shortening an older 870, but wondering if I should.
