The Brownells Bolt Carrier Group is made by a well-established firearms industry manufacturer, made to our specifications. All components of the BCG are made in-house, under one roof, not outsourced to the lowest bidder. Even the firing pin and gas key, commonly outsourced components, are machined by our manufacturer. These Bolt Carrier Groups are rigorously inspected at the factory, for hardness requirements, fitment, cam path geometry, magnetic particle inspection of the bolt and more.
