I had a post-ban Armalite National Match. It was by far the worst AR I have ever owned. Personally, I haven't had good luck with Armalite rifles so I don't reccomend them, despite thier making a good product. My FSB was constantly canted, as Armalite uses a non-standard attatchment method which is prone to coming loose. You have to loctite the hex heads, which completely negates the potential advantage of adjustments. My NM came with the wrong front sight post as did my flat tops. After my FSB was permanantly fixed, the windage was maxed and I had to send the rifle back to have the upper receiver replaced*free of charge, though it took 4 weeks*. My NM had a gremlins, hardly something trustworthy enough for a defensive rifle. Overall, I haven't been thrilled with Armalite, especially my NM model. I can say that they do make excellent guns*when they work* and they have lifetime waranty which they honor and thier CS is pretty good. Unless you are shooting at Camp Perry, you really don't need a national match rifle. I personally don't like the sights or the attributes. My NM was one of my first AR's and I was under the impression that NM models were "more accurate" and overall better rifles. I guess if you can get it for a song, by all means....otherwise, buy a DPMS, Bushmaster or Rock River standard 20 inch A2/A4. I don't think you will get your money's worth paying for the NM model.
