Is it a oval shaped piece that holds the handguard and goes around the barrel and gas cylinder? If so it's the front band and unless the gas system has been unitized (unlikely) the front band will move around. This is normal but not desirable. Look into getting a shim kit from Fulton Armory to tighen it up.
Congrats on the new rifle!
Oh, the spindle valve is on the side of the gas cylinder (left I think) and should have a slot on one side. You use a screw driver or any slotted tip to push this in and turn it 90 degrees to shut off the gas system (you should never need to do this).
