Gun Butter Trigger Grease is a high-film synthetic grease for the metal-on-metal contact points in pistols and rifles: sears, hammer and trigger pins, slide rails and locking surfaces. It comes in a 15 cc applicator, so you can put a small amount exactly where it is needed.
It is made for high film strength, a wide operating-temperature range and long-lasting corrosion protection. It stays put on high-friction parts instead of migrating or slinging off, which is the main problem with using a light oil on trigger components.
Features:
Apply a thin film to clean, dry contact surfaces. On a trigger group, a little goes a long way. Excess grease collects carbon and debris, so wipe off anything that squeezes out after you cycle the action a few times.
