Can this be used in a right side charging Gen 2 bear creek arsenal upper chambered in 7.62x39mm?

Expert Answer

A

Answered by Ethan, Gear Expert, from IL, United States, on February 13, 2023

The Cryptic 6.5mm Grendel/7.62x39mm Bolt Carrier Group would not be compatible with your BCA 7.62x39 upper. There would be no way to charge the rifle in order to load the first round into the chamber.
