Hornady Black 5.56x45mm Ammunition 75 Grain Interlock HD SBRf - 81296

Hornady Black 5.56 NATO 75 gr InterLock HD SBR is specifically designed for 10.5"–11.5" short-barreled rifles (SBRs), utilizing proprietary propellant technology and a bullet engineered with Critical Duty FlexLock design principles. This round offers exceptional performance in both suppressed and unsuppressed platforms, ensuring minimal flash and residue, a dramatically reduced sound signature, and no fouling or overheating of suppressors.

Optimized for uniform velocity and accuracy, this ammunition also delivers a controllable rate of fire in automatic platforms. Meeting FBI protocol requirements, it is the optimum choice for 10.5"–11.5" barreled 5.56 rifles, making it an excellent selection for law enforcement, tactical applications, and personal defense.

Hornady BLACK ammunition delivers superior performance for a variety of applications including direct impingement, gas piston, suppressed, unsuppressed, inertia, bolt, pump, supersonic, subsonic, rifle, mid‑length, carbine or pistol.

Features and Specifications:

  • Performance Metrics: Muzzle velocity of 2321 fps and muzzle energy of 897 ft. lbs ensures reliable ballistics in short-barreled firearms.
  • Technology Enhancements: Incorporates Hornady’s Interlock design for superior terminal performance.
  • Versatile Use Cases: Designed for tactical shooters and law enforcement, suitable for suppressed and unsuppressed use.
  • Compatibility: Ideal for 10.5"-11.5" barreled rifles, providing consistent performance across different platforms.
  • Primer and Casing: Utilizes Boxer primer and high-quality brass casing for enhanced reliability and ease of reloading.
