The Daniel Defense M4 300S Upper Receiver Group was designed for those demanding a high-performance, short-barrel rifle chambered in the versatile 300 Blackout cartridge. Built around a Cold Hammer Forged 10.3” Strength-to-Weight (S2W®) profile barrel, the 300S URG delivers .30 caliber projectiles with greater muzzle energy than comparable 5.56mm platforms. The barrel is equipped with a DD improved Flash Suppressor to reduce flash signature, and a low-profile, pistol length gas system provides smooth, reliable cycling under harsh conditions and reduces perceived recoil. Our DDM4 Rail 9.0 shields the barrel and gas block and affords ample room for securely mounting multiple accessories. Three removable DD Rail Panels made from Santoprene, which are heat resistant to 300° F, provide a secure, comfortable grip while protecting the support hand from heat, while a Daniel Defense Vertical Grip provides superb ergonomics and control. All Daniel Defense complete upper receiver groups come standard with a bolt carrier group and charging handle.
