crap, I typed out a long response on my phone, but apparently it didn't post. You can, particularly if you are patient, and don't mind blemishes. I mean a blem lower, upper + bcg can end up as little as $175 all together, and most blems I've seen I can't spot the blemish. get one of the crappy plain M4 stocks with buffer tube/buffer/spring for as low as $30 on some sales, a LPK for $50 puts you at 255. all that's left is barrel for 110, barrel nut, delta rings and plain handguard for around $50 altogether and you have a basic AR15 for just a little over $400. But its a plain jane, nothing exciting rifle. What makes these fun is they are the lego sets of rifles :D
