300 Black Out 8.3″

NOTE: We are a build to order manufacturer and all orders are built in the order in which they are received. This upper is backordered and estimated to be 8-10 weeks out. 

Our complete upper assemblies will arrive to you inspected, tested, and ready to drop-in and go to work. We maintain our high standard of tolerances and attention to detail as the uppers we use for complete rifle builds. Every built upper and complete gun is test fired before leaving our facility for function check before it reaches you. We offer several rail choices and rail lengths. Use the drop bar to make your selection.
