The Diamondback DB15 in 300 Blackout delivers proven performance for hunters and tactical shooters demanding reliable semi-automatic capability. This carbine-length platform maximizes the 300 Blackout cartridge's effectiveness while maintaining AR-15 familiarity and parts compatibility.
What Makes This Different
The DB15 combines a properly treated 16-inch barrel with a 12-inch M-LOK handguard for superior balance and accessory mounting flexibility compared to standard carbine handguards. The 7075-T6 aluminum receivers provide military-specification strength while the black nitride barrel treatment offers enhanced corrosion resistance and easier cleaning than standard phosphate finishes. This configuration optimizes the 300 Blackout's ballistic performance for both supersonic and subsonic ammunition.Key Features
