Built in New Zealand. Trusted in service.
RDX Technologies specialises in weapon sound simulation. Our patented gas-acoustic technology delivers authentic report — from small arms to large-calibre cannon — with no pyrotechnics and no live ammunition.
Our systems are in service with the New Zealand Army and the Australian Defence Force, including cannon simulation for the Rheinmetall Boxer programme.

Our story
It started with one question: why doesn’t it sound real?
RDX was founded by twin brothers Shane and Mark Hugill, raised on a farm in rural New Zealand with a figure-it-out approach to every problem. Modern simulation could replicate the look and feel of a weapon — but the sound was missing.
Working from a small workshop, they tested every sound technology they could find. Years of trial, testing and iteration produced a patented single-fuel system that is now used by military and law enforcement organisations around the world.
Today RDX engineers every component, writes every line of firmware and tests every system until it is ready for the field.
Our mission
If training doesn’t feel real, it doesn’t build readiness.
RDX systems close the gap between simulation and live fire — the sound and sensory load of the real event, without the cost, risk or logistics of conventional ammunition.
Defence forces
Scalable simulation from individual small-arms users to armoured vehicle crews. In service with the New Zealand Army and the Australian Defence Force.
Law enforcement
Sensory-rich scenarios that build muscle memory and decision-making under stress — without a live-fire facility.
Training providers
Professional-grade realism for security and tactical training organisations.
