WE-Tech Hi-Capa 5.1 T-REX Silver CO2 Air Gun (4.5mm Steel BB)
The WE-Tech Hi-Capa 5.1 T-REX Silver is a high-performance, competition-inspired CO2 blowback air gun built on the popular Hi-Capa 5.1 platform. Designed to fire 4.5mm steel BBs, its striking silver ported slide, matching silver outer barrel and trigger, black grip area, and flared magwell deliver a distinctive two-tone custom look for backyard target practice, training, and collection display.
Powered by a reliable CO2 magazine, the T-REX Silver features a crisp gas blowback system for realistic slide action and recoil impulse. The ported and skeletonized slide reduces moving mass for efficient cycling, while the ergonomic textured grip, fiber-optic front sight, adjustable rear sight, and frame-mounted accessory rail provide complete tactical utility and control.
