Im possibly looking to get another upper for my AR in a different caliber. Anyone know where i can find a list of calibers that would fit my 5.56 mm lower, ive heard the .458 and the .50 beowulf would fit because the cartridge lengths are the same.
Ill be deer hunting with it in indiana because a rifle that fires a bullet with a straight case is now legal here.
