The Jarvis Model USSS-21 pneumatically operated high-speed captive bolt stunner for cattle. New design. Lighter weight. Faster bolt speed.

The USSS-21 renders stunned animals insensible to pain with a one-shot humane, more consistent stunning procedure, due to improved and faster pressurization. With an oblong-shaped stunning rod for easier skull penetration, and 15 to 20% faster bolt speed. All that using 25% less air with no performance loss. Reimagined for the operator. Easy to handle, repair, maintain, and clean. Designed with an improved ergonomic handle for less operator fatigue, and controlling possible injuries. Featuring an auxiliary handle that rotates to the operator’s preference. And two different firing sequences – so there’s less chance of activating the stunner accidentally.
