seems like you are trolling a bit here. yes it does. You asked the questions and some of us answered. It looks likes you are defending a rifle company who's product you dont even own. Either you are validly asking the questions or you are just trying to start a fight. I am hoping you are just trying to gain focus.
I own my rifle (Spikes) and have used the living crap out of it. replaced a few consumable parts here and there and I shoot around 1k 3k rounds a month. Others people here shoot way more than me and others dont shoot that in 5 years. As far as apples to apples....I sir have an orange, I built mine and I am the warranty. If it fails its my fault and I have to pay and fix it.
as far as manufacturer warranties for the brands listed....

the others have a standing order that they will produce rifles that work period. They stand behind the mechanical product. If you call BCM and report a problem, it will get fixed I can assure you of that. Same with Noveske, Spikes DD Loki etc.
I am not trolling. Look at my original post. Any trolling there?
Some of the replys to my OP may be trolling, but I am asking questions because I don't know the answers.
I am just asking for more information, other than WAl-Mart sucks, or my gun is better than yours, or if you don't build it, it isn't worth having.
I have never owned an AR, and I may never if it comes down to popularity contest.
I will only buy one when I know what I am getting for the money, and if it is a good value.
That is why I am asking for more information.
Thanks
