Coming Soon! Purpose-built for professional end users who demand maximum suppression and control, the Sector 556 Full Size delivers uncompromising performance for 5.56mm/6ARC platforms in a combat-proven, extended-length design. Optimized for both standard and short-barreled rifles, it provides exceptional sound reduction, superior flash mitigation, and advanced gas regulation for extended engagements.
At its core is ECHOCORE’s proprietary XCR (Cross Chamber Regulation) technology, working in tandem with a long-form helical baffle assembly to stabilize internal pressures, reduce back pressure, and minimize felt blowback. The increased internal volume enhances gas dwell time for deeper tone, lower decibels, and cleaner cycling — translating to greater shooter comfort, improved accuracy, and reliable performance during sustained semi-auto or full-auto fire.
3D printed from 718 Inconel, the Sector 5.56 Full Size thrives under extreme heat and heavy round counts, resisting corrosion and operational abuse in the harshest environments. Finished in ECHOCORE’s infrared-suppressive, non-reflective coating, it minimizes both visual and near-IR signature for day/night signature reduction.
From overwatch positions to prolonged patrols, the Sector 5.56 Full Size delivers quiet authority, superior control, and mission-ready durability — engineered for those who refuse to compromise.
