The RC4 bridges the gap between the low back pressure of the RC3 and the RC2's excellent sound suppression rating to create a high-performance, general-purpose 5.56 suppressor. The suppressor features a flow-through, 3D-printed design utilizing the high heat-resistant properties of the Inconel and sports a new muzzle design that significantly reduces frontal flash detection while providing improved impact resistance. The end result is a suppressor that boasts incredible reliability and unmatched flash reduction while reducing back pressure by as much as 60%. This model features an FDE color pattern and utilizes Surefire's Fast-Attach system. A Fast-Attach compatible muzzle device is required (not included). *Sound suppression ratings are approximate based on internal testing done by the manufacturer. Results may vary depending on firearm configuration and ammunition used.*
