I am not a big fan of RRA either, but I don't think he needs to be focused on "mil-spec" unless he is planning on running his AR pretty hard.gigag04 wrote:RRAs are NOT mil-spec and I would stay far away.Blindref757 wrote:For your budget, you can't go wrong with Rock River.
You want it chambered for 5.56x45mm NATO unless you intend it to be used for varmint hunting, then you might want to actually consider getting one chambered for .223 Remington. Mil-spec buffer tubes will likely outlast commercial tubes, but as long as you buy a well-known quality brand, you likely won't be able to tell a difference just because it has a commercial tube in it.
Mil-spec is good to have, but unless you are going to be hard on your AR (i.e. competition) I personally don't think it is something you should obsess about.
You can't go wrong with Colt. I've heard great things about BCM and the S&W M&Ps. I've heard mixed things about LWRC, but have never handled one of their rifles so I will keep my opinion to a minimum.
All that said I have a ~2008 Bushmaster ORC (commercial buffer tube and all) and, since I'm not a heavy user, it has handled everything I have put it through including a couple of intense training classes. But if you have a budget of $1-2k, I would go with something a little higher end like a Colt.
