I would leave it in. I tried this on mine and once it was out and everything reattached I was not liking what I was seeing. There was quite a bit of play at the back of the receiver rail from all the weight now pulling forward. The shroud is heavy on its own plus I have a full length top rail, brush guard and a single point picatinny w/swivel mount on the bottom that the bipod attaches to. I think this is too much weight for the two short screws that hold the shroud onto the receiver, they only thread in about 3/8". If I stripped everything off it might be a little more a little more sturdy, but I think it's best to leave the barrel support in.
