There is nothing wrong with buying a complete rifle for your first. You could always build one if/when parts are more readily available.
Check the classifieds. There are several used ARs for sale there.
Also, with some new models you will at least have the backing of the factory for any troubles it may have (though most can be remedied pretty easily once you pin-point the exact problem).
