ECHOCORE Suppressors Sector 5.56 Inconel Suppressor - Black

Engineered for professional end users who demand absolute control, durability, and signature reduction, the Sector 556 Full Size stands as a purpose‑built suppressor for 5.56 NATO and 6ARC platforms. Its extended‑length architecture, paired with advanced internal gas management, delivers exceptional sound suppression, reduced flash, and smoother cycling—whether mounted on a standard rifle or a short‑barreled setup.

Constructed using DMLS 3D‑printed Haynes 282 / Inconel alloy, the suppressor features a completely weldless design, eliminating traditional weak points and maximizing structural integrity under extreme heat and sustained fire. ECHOCORE’s proprietary XCR (Cross Chamber Regulation) system works in harmony with helical reduced‑backpressure baffles, stabilizing internal pressure, minimizing blowback, and enhancing shooter comfort during prolonged engagements.

Finished in a high‑temperature, non‑reflective, IR‑suppressive coating, the Sector 556 Full Size reduces both visible and near‑IR signature—ideal for day and night operations. Full‑auto rated, HUB‑compatible, and built to thrive in the harshest environments, this suppressor delivers quiet authority and mission‑ready performance for those who refuse to compromise.
