After getting some fine sand in the trigger causing intermittent issues at a Mile High Training Class, Lowlight suggested pouring Ronsonol through it to flush it out. The xmark was tuned when the rifle was built by a gunsmith but hasn't been looked at since. After Ronsonol, I noticed loose material on the front side that looks like dried glue. Should this glue be left in place, removed, or removed and replaced? if replacement is required, what type of adhesive is recommended? Thanks!
