I'd never recommend an AR for a young shooter. And, frankly, I'd never get another one for myself. Played that game once. They are crap, compared to a bolt action rifle half the price.
And a right handed AR would be even worse for a LH shooter.
I know a 10 year old who has cleanly taken three deer with an AR in the mere .223 caliber (with close supervision by an adult). The collapsible stock makes it very nearly perfect for the little guy, I'm sure he'll get another couple this year.
RH AR works just fine for this lefty, I liked my first so well I put together a second.
