Wrong size O-ring
Ordered new O-rings for my leaky trigger that had wore out from significant use. Got the parts in a timely manner, but from using the parts sketch provided for my nail gun, the O-rings for the trigger, they are almost twice as thick as the originals, and would not slide back into the assembly. Still have a leaky trigger.
