BCM COMPLETE LOWER NO FURTHER A MYSTERY

As with the lower, It's really a BCM blem lower. I couldn't find a blem on this detail to save lots of my lifestyle. It functions 100% and is a thing I'd personally bet my daily life on. BCM® now provides a complete lower pieces kit for AR15 rifles, produced solely within the United states of america from components created from Mil-Spec AISI8620
