: from Wilmington, NC United States  
bought this upper with all of the add ons, looks beautifully machined to spec and sturdy, very excited to piece it into my new build, and see how it runs but so far my hopes are high, and love to support NC manufacturers. plan on pairing it with geissele internals, thank you MAS defense!!
