My 9 year old thinks he's ready to put some fur on the ground this year so we decided he needed a calling rifle. Of course, when I gave him a choice of AR or bolt action, he went with the AR. Anyway, this is what we came up with and he's pretty stoked.

I took one of my old 3 gun uppers and went after the stainless barrel and tube with Brownell's Alumahyde paint (good stuff) to dull it up a bit and added a Vortex PST 2.5-10x44 in a LaRue mount.
The lower is a UT Arms with a JP trigger, Ergo grip and ACS-L. I still might change out the comp so it's not so loud and possibly add an offset Burris Fast fire.
I think I might see if he'll let me borrow up.
