Daniel Defense // New DDM4 300S Factory SBR

Introducing the DDM4 300S chambered in 300 Blackout, the latest addition from Daniel Defense to their factory Short Barreled Rifle Lineup.

The DDM4 300S was designed for those demanding a high-performance, short-barrel rifle chambered in the versatile 300 Blackout cartridge. Built around a 10.3” Strength-to-Weight (S2W®) profile barrel, the 300S uses standard 5.56 bolts and magazines to deliver .30 caliber projectiles with greater muzzle energy than comparable 5.56mm platforms.

The increasingly popular 300 Blackout cartridge has proven itself to be extremely efficient in short-barrel rifles, yielding superior ballistics over the venerable 7.62×39 cartridge. With a wide variety of factory ammunition made for everything from home defense, target shooting, hunting, suppressed operation, and tactical applications, the 300S is capable of delivering exceptional performance from a compact, fast-handling package.
