Echocore Sector Full-Size, 5.56mm, Suppressor

The Echocore Suppressors Sector Full-Size 5.56mm suppressor represents the pinnacle of professional-grade sound suppression for 5.56mm and 6ARC platforms, delivering exceptional performance in an extended-length, combat-proven design tailored for demanding end users. Engineered with proprietary XCR (Cross Chamber Regulation) technology and a long-form helical baffle system, this suppressor dramatically reduces back pressure, minimizes felt blowback, and optimizes gas flow for cleaner, more reliable cycling during high-volume fire. The result is significantly lower decibel levels, a deeper and more controlled tone, superior flash suppression, and enhanced shooter comfort—making it ideal for both standard and short-barreled rifles in sustained semi-auto or full-auto applications.

Constructed entirely through advanced DMLS 3D printing from durable 718 Inconel, the Sector Full-Size features a completely weldless design that excels under extreme heat, heavy round counts, and harsh environmental conditions while resisting corrosion and operational abuse. Its HUB-compatible (1.375x24 TPI) mounting system includes a 1/2x28 direct thread adapter for seamless compatibility across platforms, and the low-flash vented endcap further reduces muzzle signature. Finished in Echocore’s proprietary high-temperature, non-reflective coating, it effectively suppresses both visual and near-infrared signatures for reduced detection in day or night operations.

With a length of 7.06 inches, 1.75-inch diameter, and a manageable 18-ounce weight, the Sector 5.56 Full Size balances maximum internal volume for deeper suppression with practical handling characteristics suited to overwatch, patrols, and prolonged engagements. Full-auto rated and built for uncompromising reliability, this suppressor delivers quiet authority, improved accuracy potential, and mission-critical durability without compromise.
