If you have excellent mechanical skills, swapping barrels will be a piece of cake. I know it's a little unnerving the first time because you are worried about doing something wrong that will cause the gun to blow up in your face or something, but once you've bitten the bullet and done it, what what a simple, straightforward job it really is.
Headspace gauges are cheap insurance you can use them to periodically check the headspacing on all of your ARs.
If you are interested in going this route, I'd recommend searching the Build It Yourself Forum for more info as this topic has been amply covered many times over.
