I'm going crazy or I'm really stupid. I'm looking for replacement barrels, and when they say "40" hole is it 40 rivets? So if I want to replace this, this is a "20" hole? If that's true will a 40 hole fit this 20 hole or do I need to buy 20 hole barrels? Googling this does not help me at all so any help is appreciated! Killing myself here looking for some replacement lips.
