So question can I shoot a 30 caliber carbine with a 300 Blackout upper, cause I just saw a video of a guy that did it and is it safe?

Where's the link bruh,We would like to see what your talking about plz!
Really thinking the video he saw was .30 carbine round nose bullets loaded into .300 BLK cases.
Select the ammo round that you want based on what you want to do with it. Most that I've talked to about hunting with an AR like to have at least a round that's around 30 Caliber. .223 and 5.56 are too small.Hi I want to build a 30 caliber carbine in an AR15 format. Anyone knows who build the barrel in that caliber?
