I don't intend to insult anybody here, but if you cannot remove the receiver assembly from the stock of a Remington M700 without assistance, you should reconsider any attempt to alter the dimensions of any part of your rifle. Free floating a barrel is a fairly straight forward process which, if done poorly can completely ruin the appearance of your gun. I would suggest you find a local gunsmith willing to either show you the basics, or give you a price you can afford for the job. Free floating doesn't always increase accuracy, either. If your rifle shoots well, then don't mess with it. Accurizing a factory rifle is not a simple process, and should be preceded by allot of research (academic, rather than internet feedback). Most of the advice here is good, but you'd have to know the difference beforehand to tell the difference. Think long, and hard before you alter a gun yourself.
