What’s Included
- Two 10-round translucent polymer magazines marked "300 BLACKOUT"
The forged 7075-T6 aluminum upper and lower receivers feature a Type III hard-coat anodized matte black finish that resists wear while keeping weight low. Marked “MULTI CAL,” the lower is paired with a direct-impingement operating system for reliable cycling of subsonic or supersonic .300 Blackout loads.
A 16-inch chrome-moly/vanadium steel barrel with a 1:8 twist delivers consistent accuracy across common bullet weights. It is threaded 5/8-24 and capped with a multi-prong flash hider/compensator, giving shooters the option to add other muzzle devices that share the same thread pattern.
The 15-inch free-float aluminum M-LOK handguard runs the full length of the barrel for maximum mounting surface. Integrated QD sockets make sling placement straightforward, while a continuous top rail provides space for sights or accessories.
Daniel Defense upgrades make this rifle stand out. The six-position collapsible stock offers a 10.5-inch length of pull at its shortest setting, the over-mold pistol grip improves control, and the vertical foregrip supports stable off-hand shooting. Inside, a silver-anodized single-stage trigger shortens reset and gives a crisp break.
Whether you want a tuned AR-15 platform for suppressed shooting or a versatile carbine for the range, this customized AM-15 delivers proven components and thoughtful enhancements in a caliber known for flexibility.
