Hugh/JR:
I own the same rifle; I just bought it last fall. Full concurrence with all Pat’s observations, but the plastic furniture can be a drawback. During repeat (not full auto) firing, the hand guard failed (melted) at the forward-most position, welding the heat-softened material to the increasingly-hot barrel.
I recommend owners of this otherwise fine product consider either increasing the gap between the plastic hand guard and the barrel or swapping it for one of different material.
