Overview

The Sub 2000 ships with a heavy, gritty trigger that breaks somewhere between 9 and 10 pounds, the single biggest complaint owners have about the gun. The M*CARBO Trigger Spring Kit is the spring-only fix: swap the factory springs and the pull drops to a much cleaner 4.75 pounds without buying a complete trigger group. It is the most common first modification on the platform and the reason M*CARBO became the default Sub 2000 aftermarket name. Install is a bench job that requires separating the receiver halves; M*CARBO publishes a step-by-step video. Because spring-only results vary slightly with each rifle's factory tolerances, owners who want a fully reworked trigger with a new bar, aluminum trigger shoe, and polished feed ramp should look at the All-In-One Pro Performance Trigger Job Bundle instead.
