Gunex Gun Oil is the perfect oil for the long-term preservation of bare metallic parts, even in extreme conditions (-50°C up to 100°C). Gunex Gun Oil removes powder and tombac residues, ensures that the complete mechanisms of rifles, pistols, and revolvers run smoothly, cares and protects. Resins of unsuitable oils are dissolved. Gunex Gun Oil creeps between metal and moisture, infiltrates hairline cracks, cleans, keeps surfaces smooth, does not get sticky or resinify either. Gunex is free from silicone.
