Diamondback DB15 350 Legend AR-15 Rifle 16" Barrel M-LOK Handguard

The Diamondback DB15 in 350 Legend bridges the gap between traditional hunting cartridges and modern sporting rifle platforms. This straight-wall cartridge rifle delivers exceptional performance for hunters in restricted zones while maintaining the familiar AR-15 operating system.

What Makes This Different

The 350 Legend cartridge provides significant advantages over standard .223/5.56 platforms for hunting applications. This straight-wall design meets hunting regulations in many states that prohibit bottlenecked cartridges, while delivering substantially more energy downrange than pistol calibers. The DB15 platform adapts this cartridge to a proven, reliable action that hunters and shooters already know.

Key Features

• 350 Legend chambering for legal hunting in straight-wall cartridge zones
• 16-inch button-rifled barrel with 1:16 twist rate optimized for bullet weights
• M-LOK compatible free-float handguard for accessory mounting flexibility
• Black Cerakote finish on aluminum receivers for corrosion resistance
• Full-length Picatinny top rail accommodates wide range of optics
• Standard AR-15 controls and manual of arms for familiar operation

Field performance centers on the 350 Legend's ballistic capabilities, delivering approximately 1,800 ft-lbs of energy at the muzzle with 180-grain projectiles. The cartridge maintains effective energy levels out to 200 yards for medium game hunting. The familiar AR-15 platform ensures quick follow-up shots and reliable cycling with quality ammunition. Weather-resistant Cerakote finish protects critical surfaces during extended outdoor use.
