556

The 556 is a high forward-pressure suppressor for 5.56mm designed to excel in demanding operational environments, providing superior control over muzzle blast and sound suppression. Engineered for a high flow rate, it efficiently channels gases forward, reducing both lateral and rearward blast propagation, which greatly enhances user comfort and safety during sustained fire.

This suppressor incorporates advanced additive manufacturing techniques that withstand extreme heat and pressure, ensuring high durability even under rapid firing conditions. Its precision-engineered internal pressure system minimizes sound signature while maintaining performance, making it ideal for tactical scenarios that require both stealth and sustained firepower.

556 carries the SOCOM Suppressed Upper Receiver Group durability rating and an unrestricted minimum barrel length, so it runs on duty-length uppers and short-barrel guns alike. HUB 1.375x24 mounting keeps mount selection open.
