Worth noting that while firearms are fairly durable goods, they do have a lot of wear when they're used regularly. Trigger pins can wiggle loose. Butt stocks can crack. Springs lose their springiness. Barrels wear down with normal use, and that wear is accelerated to corrosion if they aren't cared for properly. Receivers will crack if used enough. Sure. That gun in your uncle's safe will probably still shoot fine in 50 years (assuming it was cleaned before it was put away), but competition shooters replace their arms, or major parts in their guns every couple of years or so.
