Maverick,
You are partially correct. It's been about 20 years but I believe it's 25 yards. It's called a "Battle Sight Zero" or BZO. A bullet crosses the line of sight two times. Once on the way up, then once on the way down. The 25 yard zero will also sight you in at 300 yards (if I remember correctly). From a 300 yard zero, 500yds is not a huge adjustment.
Im sure you can google USMC Rifle Qualification and see the 500 yard qualification for yourself. The 1000 yard shooting I did was at a unknown distance course and yes we were lobbing rounds down. If I remember correctly the M16 rear sight adjustment goes out to 800yds.
The difference between a 556 "military" round and a 223 is just a few hundred fps and hand loads let you make up much of the diffrence. Most AR15's made today are WYLDE and can shoot both 556 nato and 223 anyway.
Yes I do like the 308 better and it is a longer range round but the ar is so fun and cheaper to shoot. If I had to pick one it would be either a 338 lapua or a 260 remington. The 206 will be my next gun!!!!
