Product Characteristics & Cosmetic Standards
Our products are manufactured using precision machining and industrial finishing processes. As a result, minor cosmetic characteristics may be present, including but not limited to light machining marks, tool traces, finish variations, minor surface marks, slight discoloration, or light surface oxidation where applicable.
In mechanical systems, slight movement, wobble, or play between components may occur due to designed tolerances and does not affect function or performance.
These characteristics are purely cosmetic or tolerance-related, fall within normal manufacturing standards of the airsoft industry, and do not constitute a product defect.
Returns or warranty claims based solely on such cosmetic or tolerance-related characteristics may therefore be declined in accordance with our return policy.
Light surface oxidation (rust), where applicable, is a normal material property and can typically be removed through routine maintenance (e.g., WD-40 and a soft brush).
