Great info guys keep it coming. I had thought of a new upper but seems like I don't take as disciplined shots with my ARs. I just can't help myself from rapid succession shots. Its the kid in me I guess. Give me a bolt gun though and I tend to take each shot more seriously. Iwill take a look at the Savage line. I have a friend with a model 12 and its been very accurate for me.
If you set it up right and take some time you can make some really long shots with the AR platform. Rock River Varminter upper with 1/7- 24" stainless.
I have changed the glass to a Bushnell Trophy series since this pic. It has taken Coyote at 250 yds no sweat. 62 gr Hornady no wind.
