Liked the M-4 I carried well enough for the job at hand, but for yotes... can't justify losing 200+ fps. I know it's not a lot but it's enough to make a difference.
Totally depends on your setups and terrain though. If you're not shooting anything past 350, there's nothing wrong with that AR, except you'll have to remember that hitting with the first shot is ideal. It's hard to do when you know you've got 29 more bullets as far away as a trigger pull
