Minus the Aimpoint, which isn't great in low-light, all good points, BuzbyYou like .223, quick follow up shots, and a wide field of view.
An AR15 with an aimpoint is clearly the answer;
Infinite field of view
Follow up shots don’t get any quicker or easier
just so happens to run 223 quite well
Added bonus for being compact, light weight, and practically indestructible
If only this newfangled AR design you speak of would catch on. Just kidding. It is astonishing how many hunters discount the AR-15. It's ideal for this exact situation.
