Guarder springs are performance consistent even after thousands of shots, and unlike cheap springs, their performance matches their rated stiffness. Guarder is a renowned Taiwanese brand known for producing quality parts. Thanks to its focus on precision and quality control, Guarder has earned a solid reputation among airsoft upgrade parts manufacturers.
