the 700 is what the m24 is based on I believe, and some of the 700's are top of the line while others are more basic. Pretty much use how much it costs as ameasuring toolfor how good remington percieves it to be. As with many things, you get what you pay for. The 700's range from i guess the one you see at walmart to a few that cost over a grand. I think the ADL was replaced with the DM(detachable mag) but im not sure. if you go to their web site you can see a list of all the 700's they are currently making. I am looking into them myself, although I am looking into a larger calibur. The 700 claims to be the rifle all others are measured up to, weather that is true or not I am not sure, but i hear they are good rifles. happy hunting.
