Design Intent

Mercury Precision engineered this lower parts kit around a straight trigger shoe that maintains tight tolerances throughout the fire control group. The match-grade design reduces variance in trigger reset and pull weight, delivering more predictable trigger performance than standard mil-spec components. This kit is built for shooters who understand that trigger quality matters but don't need exotic features or ultra-light pull weights.
