Thanks for all the input guys! I guess i shouldve started with the fact that im not new to rifles, as a whole. I currently have a eddystone model of 1917 and a glenfield model 60. Im just wanting to branch off the pistols and go more towards "assault" rifles. One question ive been kinda scared to ask is whats all this i hear about a .223/5.56 AR... Is that rifle able to shoot both rounds straight outta the box?

You can use both in a 5.56 rated rifle. You should not use 5.56 in a .223 rated rifle.

My first semi was an M1 Garand, its far from tactical and aint the cheapest shooter but its a must have in my opinion.

The critical difference between the .223 and 5.56 is pressure. 5.56 is a higher pressure round, .223 is the lower pressure round. Obviously, bad things can happen when you mix those up in the wrong order.

Just plan on a 5.56 rated chamber.

If you like power in a semi, the Garand is a rush. Great iron sights, too.

ScottA is right about the pressure but there is a little more to it. The 5.56x45 chamber has a longer leade (distance of the bullet to the riffling) than the 223 to compensate for the higher pressure which is only about 10%. The bad part come when you load the higher pressure round in the shorter leade of the 223 chamber. A 10% over pressure can jump to 30+%.

A buddy of mine bought a Stag Arms AR and loves it. $900 new. Worth taking a look.
