Originally called .300 Whisper, the .300 AAC Blackout was designed to achieve energies similar to the 7.62x39mm Soviet in an AR-15 while using standard AR magazines at their full capacity. Our whisper-quiet subsonic rounds feature 220 grain projectiles for maximum ballistic energy.
50 round quantities are packaged in our signature clear, plastic containers.
250/500/1,000 round bulk quantities are packaged in 6 mil plastic bags with an enclosed desiccant pack to ensure dryness if stored long-term.
Proudly manufactured by American workers in Novi, Michigan.
Please Note: Our .300 Blackout 220 grain subsonic ammunition has been tested to function in several rifles with barrel lengths from 10.5" to 16", with and without suppressors. However, rifle setups vary widely and you may need to adjust your gas settings and/or swap buffer weights to find the best performance for your weapon.
