For a scope, look at a Burris Fullfield II 3-9x40. They are cheap and in my experience rock solid reliable. They are not a dialing scope, but if your shooting deer with a 223 you probably are not shooting much past 300 yards, so it’s not needed.
Not my first choice but I put one on a light weight Kimber 6.5cm for up close work. It took at least 2 falls, one pretty hard in a hail/t-storms and still was zeroed. That rifle took a mature bull elk and a moose after all the abuse.
For the weight and cost it's pretty hard to beat, especially if you're looking a Leupold instead.
