It went in easily and came out just as easily putting heat to the receiver again when I changed my mind. Other than that, snug barrels usually only require putting the muzzle down on something padded on the floor and pushing the receiver down.
I use this one. It is recommended for Billet receivers so you don't warp the receiver.[ATTACH=CONFIG]4730[/ATTACH]
