The new 300 BLK Cleaning System was specifically created by Otis to clean rifles chambered in the increasingly popular .300 AAC Blackout. .300 Blackout and .300 Whisper cartridges for the AR-platform are flying off of shelves, but they can also be some of the dirtiest rounds in the industry. Otis saw that, and the .300 BLK kit was born.
