Birchwood Casey Tru-Oil Gun Stock Finish

Tru-Oil is a professional-grade wood finish specifically engineered for gun stocks and musical instruments. Originally formulated by Birchwood Casey, it is a specialized blend of linseed and other natural oils that dry quickly and resist water damage, providing a durable, high-gloss finish. The product is widely regarded as an industry standard for restoration and protection of fine wood furniture and firearms.

Birchwood Casey was founded in 1948 and established its reputation in the shooting sports and wood-care markets from its headquarters in Minnesota. Today, the brand is part of the GSM Outdoors family, a major American holding company specializing in outdoor and shooting sports accessories. The manufacturing process remains primarily based in the United States to ensure quality control for its chemically sensitive formulations.
