Complete SBRs in 300BLK

[LiquidTension]

I'm hoping that my 10.3" DCA barrel arrives tomorrow

Lucky you. I called them yesterday and they said barrels are backordered 20-26 weeks, there are over 500 people on the waiting list, and they won't be $169 by the time they get caught up. Thankfully Innovative Arms is going to cut me a barrel from a Shilen blank so should have mine up and running next month - on the Warfighter Advanced Receiver no less
