Even if my rifle has a "shroud", my hand would still get burned if I choose to hold the fore end of the gun closer to the muzzle, where the barrel isn't covered. If it doesn't stop my hand from getting burned, then it's not an attribute of an "assault weapon".It's not a shroud unless it stops your hands from getting burned? None of my guns have shrouds then because when I mag dump 4 or 5 mags in a row I can feel that heat and it burns.
If the bill sponsors wan't to play B.S. word games, I'll play too.
