The Luth-AR Titanium Nitride Trigger, Hammer, and Disconnector Set (Luth-AR part no. LRPKTHDTIN) replaces the three core fire control components in an AR-15 lower with parts coated in titanium nitride, a hard, low-friction finish that helps the trigger, hammer, and disconnector move against each other more smoothly than bare steel. Because all three parts are matched and coated together, the set installs as a coordinated upgrade rather than requiring you to mix and match finishes from separate purchases. It is a straightforward way to improve trigger feel and long-term wear resistance on a standard AR-15 lower.
