I put mine on yesterday and went out today with a screwdriver for my first outing. I also put in a CSS puc. Shot Remington #6, 2 3/4 & 3 '00' and 2 3/4 slugs - I forgot to get grab the cheap stuff when I went out the door. Wow! Didn't have to adjust one bit! My measure was where the cases were landing - and they all were on top of each other. I'm a newbie to the 12, and when I converted it, I just changed over the stock gas plug (the AK video convinced me). All I can say is from what I've seen so far - I'm glad I got it. Gonna send some crap through it tomorrow if I get a chance.
