I have several kids myself and am very astute at reading their expressions. Your child is clearly saying, "Puhlease, this is a fake laser-based shooting gallery that I can find at any cheap county air. I need the feel of a real 12 gauge shotgun in my hands while I slaughter Bambi for the needs of our family table."
Granted, I could be off a little on the verbiage, but I should be pretty close.
