Daniel Defense’s new caliber option, the 300 Blackout, was originally designed to give the shooter a 30 caliber projectile which could be fired out of the AR platform without an increase in magazine size while still utilizing a standard bolt. The 300 Blackout is 7.62x35mm which gives the shooter similar ballistic qualities as the .308 and the 7.62x39mm, the AK round, without having to give up the light weight 5.56mm/AR platform. The 300 Blackout can still utilize standard AR magazines without a reduction in magazine capacity. Unlike the 7.62x39mm, the 300 Blackout cartridge is still light on the shoulder with similar recoil to the 5.56mm.
