Has anyone actually needed any of their spare parts?
I've had to replace a magazine spring on a shotgun, but no replacements on the AR. At least not yet. However, I shoot them more often than I do my other guns so there will likely come a point when I will need to if I continue shooting them often. Gas rings, extractors, extractor springs, action springs, etc. are pretty much wear items. Same with magazine springs.
Of course, how often you shoot will dictate when/if you ever do need to replace anything.
