This custom sub-sonic 300 AAC Blackout load features the Sierra Match King projectile. This ammo is especially effective when used with a supressor in short-barreled rifles or AR pistols (where legally permitted), but is still subsonic on a 16" barreled rifle without a supressor. Each round is carefully crafted using using clean-burning (low-flash) Vihtavuori powder and loaded in new Starline Brass to deliver the optimal performance and consistency. This ammo uses CCI Mil-Spec primers to offer better protection against slamfires and requires an the AR-15 platform firearm with standard firing system.
