I picked up a copy of Shotgun News the other day.

I see lots and lots of ads for low priced ARs. The ones that caught my eye are the ones that say "kit" and come complete except for a stripped lower. They are going for about 500 bucks.

I've not built one before and was wondering;

How good are most of these? Are these usually pretty cheap in quality?

What would the lower parts run about?

Unless I was an armorer I should just by RRA, Olympic Arms, Bushmaster, etc?
