PCC fire control components—triggers, disconnectors, hammers, sears, and complete fire control group assemblies—upgrade the factory trigger feel on competition carbines. Drop-in and semi-custom options reduce pull weight to competition-legal minimums, eliminate creep, and deliver the crisp reset needed for fast splits at USPSA PCC classifier speeds. Compatible with Glock-pattern, Colt-pattern, and dedicated AR9 lower receivers. Fast same-day shipping on most orders at Shooters Connection.
