Here is a trigger I modified while taking time to record the manufacturing process. Please bear in mind that this is during manufacture and it does not yet have grease or bluing on it.

This rifle is capable of this (or rather, I'm capable of doing this, with my 20/55 sight; I'm sure the rifle's much better):
