Construction & Reliability

The Hi-Capa 5.1 TREX uses a metal slide and frame to deliver realistic weight (approx. 1000 g) and dependable cycling under rapid fire. The robust build supports sustained use in skirmish environments, while WE’s established Hi-Capa architecture ensures solid parts availability and compatibility for maintenance or upgrades.
