I know this is a dumb question but I am going to put it out there anyway. What is the best, inexpensive i.e. under 1k ar-15 that I don't have to build. I have heard good things about CMMG. Anything wrong with DPMS, Bushmaster? Suggestions? I am looking for a rifle for home protection, target practice, and maybe even to convert to a deer legal round later. I want something good but versatile. Thanks.
