Built for high-volume backyard shooting, this CO2-powered BB air rifle delivers full-auto action with a 400-round reservoir and .177 caliber BBs at up to 430 FPS. Its functional bolt action and included sights make it straightforward to set up and use, while the brown polymer stock keeps the design light and suited to regular outdoor handling. With a cyclic rate of 2,000 rounds per minute, it is aimed at shooters who want a fast, range-focused air rifle rather than a precision target setup.

- CO2 power means the rifle depends on cartridges, so ongoing operating cost and performance will vary with CO2 supply.
- The .177 caliber BB setup and 430 FPS velocity are suited to recreational shooting, not traditional hunting use.
- Full-auto firing and a 400-round reservoir prioritize high-volume shooting, but that can also mean faster BB consumption.
- Included sights help with setup, but the product description does not indicate any additional optics or accessory package.
