Just brought home my new Mini 14 Tactical chambered in 300 AAC Blackout. My rifle has no flash hider and has 10 round magazines to be compliant. The 2 magazines are marked 300 Blackout but I cannot find any similar ones for sale on the net. Want to know if standard Ruger .223 10 round magazines would work for this.My FFL that I bought the rifle says he was told Ruger only made 100 of these rifles. This could be a test sales in compliant only states in my opinion.
