NFA item. 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.
