We believe in quality and reliability when choosing a bolt carrier group, so we only sell fully assembled BCGs from Toolcraft. We don't add any inferior plating to raw carriers or use random bolts to complete our setups. Everything is assembled and inspected by Toolcraft, inspected again by our team and sold straight to the customer. Contact us if you have any questions!
