Does this upper come with a bolt carrier group? And if not can i just use my bolt carrrier group from my 556 ar?

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on March 11, 2022

The Radical Firearms 10.5 in. 300 AAC Blackout Upper Assemblies that display "w/ BCG and CH" will come with a bolt carrier group and charging handle. If you purchase a model that displays "w/o BCG and CH" then it will not include a bolt carrier or charging handle in which case you can use your original BCG or any BCG designed for 5.56/.223.
