When you break down a platform piece by piece, you realize that every pin, spring, and tolerance has a specific job to do. There is no fluff in a good build; if one small detail is off, the whole system feels it. Surface-level cleaning is fine for a quick range day, but if you really want to trust your setup, you have to know it inside out. For me, taking the time to properly tear down and inspect every component is where real reliability is built.
What part of your routine do you pay the most attention to when working on your gear?
