Please relieve my ignorance

I know if an ad says stripped lower/upper you have to add parts.

But if it says complete upper or complete lower does that mean I can buy a complete upper/lower and just add it to the other without and extra parts being needed?

For instance I would like to buy a "complete" lower one brand and add a "complete" .22 uppper of an other brand.

Thanks for the help.

If you are talking ARs, uppers and lowers can USUALLY be interchanged. A bolt, bolt carrier and charging handle are normally required extras.

Yes all you need is a complete lower and a complete upper.

If you buy a truly "complete" upper than Yes, all you need is a complete lower (and a mag of course) and then you've got a functional rifle. But I say truly complete upper because many times what's advertised as a complete upper, excludes the bolt carrier group and the charging handle. So keep an eye out for that when reading. Charging handle is cheap($25) and readily available but your BCG will be another $100 to $200 and might require some shopping around.

Thanks fellows.

It's all learning from here man - I just got my first AR about 2 months ago and have been learning ever since. I can't take credit for this link but there is loads of great AR info on it so I'll pass it along to you. I have found all sorts of good stuff here...
