Echo Zulu Defense X2R

Description

Second-generation flagship 5.56. The X2R brings our patented ReFlow gas-recirculation design to a lighter, harder-use package — in lightweight Titanium (X2R) or full-auto-rated Inconel 718 (X2R-HT). The HT adds a patent-pending heat-shielded blast chamber that holds suppression more consistent shot-to-shot as the can heats under sustained fire.

• Second-generation flagship — the direct successor to the X1R in 5.56.
• Patented ReFlow gas recirculation extends dwell time for more suppression in the same footprint.
• Titanium for the lightest carry, or Inconel 718 (HT) with a patent-pending heat-shielded blast chamber for sustained full-auto.

• Second-Gen Flagship – Direct successor to the X1R, rebuilt from the core and measurably improved. • Patented ReFlow Recirculation – Gas cycles back through the can instead of dumping out the bore, extending dwell time (US Patent 20260104220). • Multi-Path Helical Flow – Spiral pathways slow and cool gas for more suppression in the same footprint. • Two Material Builds – Lightweight Titanium (X2R), or full-auto-rated Inconel 718 (X2R-HT). • HT Heat-Shielded Blast Chamber – Patent-pending localized shielding on the IN718 build; holds suppression steadier as the can heats under sustained fire. • DMLS-Printed In-House – Single-piece core, inspected to the finest tolerances, Cerakote finish.
