RR,

I appreciate all the help you have provided on this subject. My brother has a Bushmaster AR-15 and we have a couple of mutual friends that have AR-15's, but these guys barely ever shoot and they only bought the guns because they looked cool on display in the local gun shops here. My brother is about the only one that can shoot them decently, and I truly hate the trigger on his gun and our buddies' guns. I know quite a bit about shotguns and bolt action rifles, but will readily admit that I am clueless regarding AR's.

It took me a couple minutes to figure out what RRA meant, but I finally figured it out. I just got back from Rock River Arms' website and had checked that one out too on several occassions but never paid attention to the fact that they sell lowers separately. Do they sell an AR-10 lower, or is the AR-10 and AR-15 lower the exact same thing, with the upper being the only difference between the two rifles? For $400 each, I'd order both lowers today and then deal with getting uppers later because I really like the thought of an upper on these guns that is chambered for a magnum type cartridge. Might even start out with an upper for the AR-15 from Accuracy Arms. I was looking at their Leviathan uppers and that looks like an awesome cartridge. I'll have to look a little closer at ballistics and powder consumption, but it looks awesome.

Other than Accuracy Arms, are there any other uppers that you would recommend?

How about glass for these guns? I love Burris and was thinking about putting Burris Black Diamond or Euro Diamond scopes on both guns. The scopes have a 30mm tube. I was thinking about putting something on them around 4-16 with a 44mm bell? Would that be too little, too much, or just enough magnification. I have a 3-12x 44mm on my .300 Win Mag and .270 bolt rifles and a 8-32x 44mm on my .220 Swift bolt rifle.

With all these options, I am really getting excited about this purchase, but I am also getting a headache.

Can you PM me with some AR boards where I might be able to learn a little more about these guns before plunging into two of them?

Again, thanks for all the help.
