DPMS Lower, Del-Ton M4 1x7 16" Upper.
She seems to be a natural at shooting it, as well. Very minimal training. Only the second time she's fired it. 27 shots from 50 yards using a table (no assists from blocks, bipod, etc... elbows on wood). Standard NRA 50 Yard Small Bore Rifle Target w/ 3.89" Black (NRA #TQ-3/1).
She'll more than likely be using it when she attends a local Appleseed Project event: Atlanta, TX Sept 24-25. I only say "more than likely" because I'm still contemplating removing the scope from my 10/22 and installing Mil-Spec sights on it, and having her use that instead. Cheaper on the ammo side of things.
