- JK Armament took 2nd place with the .30 caliber JK 155 SBRX at the 2023 Silencer Summit, and describes the G.O.A.T. HF as building on that result as its first 223/5.56 suppressor.
- The G.O.A.T. HF can be as compact as 3.3 inches and 4.4 ounces, or as quiet as possible in its full configuration of 7 inches and 13.4 ounces.
- High-flow baffle and front cap designs reduce blowback, backpressure and sound at the shooter's ear.
- A JK Taper Mount compatible with more ASR-spec muzzle devices, and a refined G.O.A.T HF end cap that greatly reduces muzzle signature, especially paired with a JK Armament .22cal War Eagle.
