We do not recommend applying lubricant to the internals of your TriggerTech Excalibur trigger. Lubricants can attract dust, dirt, and debris, which may accumulate over time and form a gummy residue that can interfere with proper trigger function.
For maintenance, we recommend cleaning the trigger using lighter fluid. Lighter fluid is effective at flushing out debris and moisture while evaporating cleanly without leaving behind residue.
If you have any questions regarding maintenance or care of your TriggerTech Excalibur trigger, please feel free to contact TriggerTech Support.
