The mil-spec lower parts kit is adequate. It does the job it was designed for. The trigger, hammer, disconnector, detents, springs, and roll pins are perfectly suited to the job of making your lower (and the rest of your AR) work as intended. As with the old adage "if it ain't broke, don't fix it," Spike's Tactical gives you their standard lower parts kit. All the parts and pieces conform to exact mil-spec standards, but with one difference: more care has been put into its creation resulting in better fit and finish. This better-than-mil-spec lower parts kit ain't broke, so it wasn't fixed; it was just made better than your mil-spec lower parts kit. See below for more info.
