WE-Tech Hi-Capa 5.1 T-REX Silver Gas Blowback Airsoft Pistol
The WE-Tech Hi-Capa 5.1 T-REX Silver is a competition-inspired gas blowback airsoft pistol built on the popular Hi-Capa 5.1 / 2011-style platform. A silver-finish ported slide, matching silver outer barrel and trigger, flared magwell, and contrasting black grip area create a distinctive competition look for lawful airsoft gameplay, target practice, and display collections.
Powered by Green Gas, the T-REX Silver features a cycling blowback slide for responsive operation. Its skeletonized slide with lightening cuts helps reduce moving mass, while the adjustable hop-up, fiber-optic front sight, adjustable rear sight, ergonomic textured grip components, and frame-mounted accessory rail provide practical functionality for compatible airsoft setups.

Frequently Asked Questions
What gas does it use?
The WE-Tech Hi-Capa 5.1 T-REX Silver Gas Blowback Airsoft Pistol runs on green gas loaded into its gas magazine. Keep the magazine seals lightly lubricated with silicone oil, and store magazines with a small amount of gas in them to keep the seals seated.
What is the FPS?
Approximately 300–330 FPS with 0.20g BBs as specified for this model. Actual readings vary with temperature, gas pressure or battery charge, BB weight, and hop-up setting, so always confirm against your field’s chrono limits before a game.
What is the magazine capacity?
The magazine holds approximately 30 rounds. Actual loading can vary slightly with BB size and loading technique — a speed loader makes topping up faster and helps avoid feed-lip damage.
Is the hop-up adjustable?
Yes. The hop-up is adjustable, so you can dial in lift for your BB weight. Adjust in small steps and test between changes — small movements make a visible difference downrange.
What is included, and what do I need separately?
The package contents are listed in the description above. BBs and gas are not included and are sold separately.
What warranty and shipping cover this item?
It is covered by the Airgrix 30-day limited warranty and ships from our California warehouse. At $235.99 it qualifies for free US shipping on its own (free on orders $59+). Returns are handled under the store returns policy — see our Ordering, Shipping & Warranty FAQ page for the details.
