CORE15 ® 300 Blackout
CORE15® is proud to introduce our new series of 300 Blackout Rifles! Since its SAAMI approval in January of 2011, the 300 Blackout has spread rapidly throughout the AR market. Utilizing the same upper, lower, bolt, and magazine as an AR-15 in .223/5.56mm, the 300 Blackout is the perfect solution for a well needed 30 caliber, compact, semi-auto rifle that is extremely versatile. CORE15® has answered the demands for this compact 30 cal. rifle by offering four different variations of our current production rifles that are equipped to handle the 300 Blackout.
