Smokingfrog beat me to it. Bushmaster stripped lowers for $49.99:

Heck, the transfer fees will add 50% to the price! And I won't get too worried about being on a 'list' since I already have a CPL. I'm on the list already.

Anyone who posts or even lurks on FreeRepublic is certainly on at least one “list.”

You don’t want a “sttripped lower,” they are considered to be a firearm and have to be purchased through and FFL, so the AR you put together has to be registered. If you buy an 80% lower, it’s considered a non-firearm (under the Federal Firearms Act of 1968) and you can get it at places like this:

Home-built AR’s are legal under the same Act, and they do not have to be serialized or registered.

You can get a “fixture” that guides an end mill to cut the FCG and to drill for the necessary pins (there are only two). A milling machine is helpful, but you can also do the work on a good drill press.
