The Daniel Defense M4 300 Pistol, equipped with the SB-Tactical SOB Pistol Stabilizing Brace, was designed for those demanding a high-performance firearm chambered in the versatile 300 Blackout cartridge. Built around a 10.3” Strength-to-Weight (S2W) profile barrel, the 300 Pistol 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 7.62x39 cartridge. With a wide variety of factory ammunition made for everything from home defense, target shooting, hunting, suppressed operation, and tactical applications, the 300 Pistol is capable of delivering exceptional performance from a compact, fast-handling package.
