AR n00B here. Search did not find anything.
In planning for my AR build which upper caliber should I get: .223 or 5.56?
I have read that a 5.56 upper can use .223 but a .223 cannot use 5.56 (due to the added "power" of the round).
Ammo wise which is cheaper .223 or 5.56?
Which is more avaliable?
Reloading wise do I need to worry about either?
Plans for this AR would be just as a learners AR. It won't be SHTH or defense. That is what SG and AK are for. Won't be doing compeition shooting either. The AR will have primarily a .22 upper and this other upper will be used as "backup" to bring the shooter up from .22 to bigger round.
Thanks
