I am thinking of buying a Model 1 upper half and I have no idea about whether it should be .223 or 5.56mm. Any opinions about which is a better choice and reasons for those opinions would be gladly accepted.

Thanks

I'd get the 5.56mm because then you can shoot both kinds of ammo.  The .223 would only allow you to shoot .223 Remington and not 5.56mm NATO rounds

5.56 will shoot in a .223 chamber.  The .223 chamber is a little tighter and *might* cause some extraction problems, especially if you use Russian ammo.

You defenitly want the 5.56mm.  There is no price difference, and as was said the 5.56 will allow you to use shitty Russian ammo, if you decide to.

Wish I would have known that before I put about 5k rounds of M193 through my .223 DPMS barrel! [@:D]

DPMS and RRA use a chamber somewhere between the two.  RRA uses Wylde.  There has been much info at this site on problems/ dangers of shooting 5.56 in a .223 chamber.

Yes, there has, but most of it is overblown.  I have fired many thousands of rounds of 5.56 in my .223 chambered AR's with no problems, either pressure signs or feeding.

Ive given up listening to the arguments about shooting 5.56 in 223 chambers.

I'm just going to purchase a 5.56 upper since it seems either round isn't a problem (we all seem to agree) in this choice.
