The only reason to go to a 223 AI is to increase the performance with the larger bullets (70 to
90 grs) If the twist is 1 in 10 + the bigger bullets won't work very well.
The AI will push the 35 to 55 grain bullets from 100 to 150 ft/sec faster because of increased
The round will fit the same mag as the 223 and can even be fire formed using standard 223
loads with good accuracy.
The only thing I can think of that would change is the port pressure and that would have to
be addressed by using an adjustable gas block.
I see no reason that it could not be done.
