718 Inconel 3D-Printed Construction

Durable 3D-printed 718 Inconel construction throughout. The Inconel alloy provides exceptional heat resistance and strength for sustained hard-use firing schedules. Weldless 3D-printed design eliminates traditional weak points associated with welded baffle construction.

SOCOM Stress Test Rated

Passes SOCOM Stress Test for durability. The SOCOM stress test represents one of the most demanding suppressor endurance protocols—confirms EOS-556 suitability for hard-use military and professional applications.

Low Back Pressure Design

Low back pressure design reduces gas blowback toward the shooter and minimizes bolt velocity spike on host weapon. The design maintains reliable weapon cycling while protecting shooter comfort and component life.

Integrated Flash Hider

Integrated flash hider reduces visible muzzle signature. The integration eliminates need for a separate flash hider on the host weapon.

HUB Compatible

HUB compatible (1.375x24 TPI) interface provides mounting flexibility across HUB-compatible muzzle devices. Includes titanium direct thread 1/2x28 mount for immediate installation on 1/2x28 threaded barrels.

K-Length Form Factor

Short K-length suppressor profile minimizes overall weapon length. The compact dimensions maintain maneuverability on SBR and carbine platforms while delivering class-leading suppression in the K-length category.

12.5 oz Weight

12.5 oz provides lightweight construction for Inconel suppressor. The weight maintains weapon balance on short-barreled 5.56 platforms.
