This video shows me installing a Yankee Hill free float tube. It was an easy go but I highly recommend buying the block for the front sight base. Taking off the FSB was the hardest part of the whole process. Instructions below
Apparently there are some guys out there who must know everything about building guns, however, they are confused.
From the instruction sheet: Screw the barrel nut onto the upper receiver until it is tight by hand. Using our forearm wrench (YHM-9621) tighten the barrel nut until the next gas tube hole lines up with the upper receivers gas tube hole(using a rubber mallet). Take special care in aligning the gas tube hole in the receiver to the gas tube hole in the barrel nut. See diagram to the right.
