Kakashi, member, from NV, United States, asked on July 22, 2022

Can .223 be shot out of this 5.56 nato barrel with 5.56/.300 BCG?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on August 04, 2022

Yes. If a barrel is stamped "5.56" then is is safe to use .223 as well as 5.56. A 5.56 BCG will function for .223, 5.56, and 300 Blackout.
