up 76,
IF you buy a new 223 or get an accessory barrel it will (should) be 1:9 twist. You need to go back a few years to get a 1:12 twist 223. FWIW, I had a 1:14 Twist 223, apparently someone got the 223 and 22-250 blanks mixed up, so it is always good to verify the twist rate no matter the vintage of the barrel.

Why be difficult, when with a little extra effort you can be impossible?
