The AR format seems to rule the modern rifle scene, but I think the .223 is just too small for an all around rifle. My buddy loves his AR-15, but I personally think the .223 is simply not enough power for people, deer, and paper.
First rifle, right? So you have an educated opinion about calibers?
Okay. Let's look at the scrawny 5.56x45 -- still in use by our troops, still putting opposition forces down, still putting lots of holes through paper, so long as you can afford to shoot and maintain it.
Can you take a deer in WA with a sub-.30 caliber round? I know a lot of states have game laws where it has to be .30/6MM, or better. But if you had to, could you? With proper shot placement, the most likely answer is yes.
Your first rifle should ideally be the one that you learn marksmanship on, which doesn't have to be 7.62x51 -- that's some expensive learning. If you're dead set on one rifle, and one rifle alone, the AR is a killer platform, with its switchable uppers. Or, you could drop $180 on a Ciener (sp.?) .22 conversion and bust caps through an AR for pennies, even if it isn't quite as accurate as a dedicated upper.
ARs do run with a dirty system, those that aren't piston-driven, but piston systems tend to introduce some wiggle and flex into the firearm. POF uppers might have reduced this somewhat, but the tendency is there. Really, a battle rifle is a minute-of-chest proposition, so I wouldn't sweat minute accuracy issues. AK platforms have sent millions of people to their maker on every continent -- ask them what they think.
Also, ARs in 5.56 use a smaller and lighter projectile -- not a small thing if you happen to ever have to carry a substantial amount of it around. Bigger cartridge, more weight -- smaller cartridge, less, with an even greater number of rounds. Just something to think about.
I'm a firm believer in 5.45, myself. The round is absurdly cheap, still readily available as surplus, available commercially, and battle-proven. AK-74s will run under just about any condition, and represent a substantial weight savings over equivalent AR and AK-47 systems, given ammo and magazine weight.
