GUNCER - GUN TUNING WITH CERAMIC ADDITIVE For precision shooters, hunters and law enforcement, long or short guns. Ceramic additives ensure functional performance and shooting accuracy Reduces wear and tear on the weapon Smoothes roughness peaks (under load, roughness peaks of the friction points are plastically deformed by flow smoothing with minimal loss of substance, friction is reduced) Reduces power losses when reloading self-loading pistols and rifles (even with weak ammunition), resulting in fewer malfunctions Excellent corrosion protection, prevents fretting corrosion Temperature range from -40°C to +210°C Ceramic additive even ensures lubrication up to +1000°C Water resistant & does not resinify Without silicone and PTFE additives GunCer is resin-free and does not resinify. Please note: PTFE (Teflon®) causes long-term damage to your gun when oil gets into the barrel.
