The AUG A3 M1 in .300 Blackout applies the bullpup's length advantage to the suppressor-optimized cartridge. A 16-inch barrel in a 28-inch overall length creates one of the most hearing-safe suppressed host rifles available. The AUG's rotating barrel gas system cycles reliably with both supersonic and subsonic .300 BLK loads. A niche but growing configuration for suppressor-focused buyers. Type: Rifle Action: Semi-Automatic Caliber: .300 Blackout Capacity: 30 Year introduced: 2018, Austria Weight: 8.3 oz Overall length: 28" Status: Active Intended use: Tactical / Defense, Home Defense
