CICO® Gunspray GS 77 400ml spray can

Synthetic High-Performance Lubricant for Handguns and Long Guns
CICO® GUNSPRAY GS 77 is a synthetic high-performance lubricant for the maintenance, cleaning, and preservation of handguns and long guns. Due to its excellent viscosity, creep ability, and surface tension, the spray reliably penetrates into the finest gaps and permanently protects even heavily stressed and fast-running weapon parts from wear and corrosion.
Cleans, lubricates, and preserves in one step
CICO® GUNSPRAY GS 77 reliably removes powder and residue from smoke as well as older deposits. Oxidized, seized, or gummed parts are loosened, smoothed, and permanently protected. The resulting ultra-thin dry sliding film is hardly noticeable, yet it is highly water, dust, and dirt repellent – ideal for everyday hunting.
Material-friendly & long-lasting protection
The synthetic lubricant does not attack blued surfaces or common plastics, wood, or alloys. It cares for and conserves all weapon parts inside and out and reliably prevents corrosion, even in adverse weather conditions. Thanks to the mineral oil, silicone, and PTFE-free formulation, there is no gumming.
Designed for high temperatures and heavy loads
The protective and lubricating film remains stable even under high mechanical stress. CICO® GUNSPRAY GS 77 is high-temperature resistant from −28 °C to permanently +270 °C (temporarily up to +300 °C) and is therefore ideally suited for moving and high-speed weapon components.
