.300BLK SBR Stack-up

The .300BLK cartridge has taken hold very quickly, and AAC has done it’s due diligence to ensure that the various components they offer for the caliber are available. The caliber runs optimally on a SBR with a suppressor. Several top manufacturers are now producing their own carbines chambered in .300, and we’ve received a lot of questions about what models are available and what we recommend. Here is a sampling of some of the more popular models:
