The RetroArms brand is based on the purely czech company Retro FACTORY s.r.o. Representatives of the company have experience with airsoft since 2001. In the beginning, the company was mainly a trading company, where the main activities were the design and commissioning of components for cooperation and assembly into functional units.
RetroArms does not compete with cheap chinese producers, but relies on the original design and high quality of manufactured parts.
Since 2013, it has a new production hall, CNC machine tools for machining complex components, a parts warehouse and a team of experienced workers and developers.
