H2S Hybrid: AR Two Stage Drop in Trigger Built for PCCs

Stern’s H2S Hybrid was developed with pistol caliber carbine and defensive shooters in mind. The Stern Defense Hybrid 2 Stage trigger bridges the gap between Mil-Spec style trigger groups and over light competition triggers with a reliable smooth pull.

The Stern Defense two stage trigger is a direct drop in replacement for your existing trigger and has endured a 250,000+ round torture test without failure. It features a smooth 2 lb first stage, leading into the positive 4 lb second stage that ends with a crisp break and predictable reset.

Light triggers are associated with light springs and reliability issues. With the H2S duty spring in place, gone are the days of inadvertent bump fires and failure to reset that plagued PCCs. The high reciprocating mass on pistol caliber carbines make light poundage short reset triggers problematic.

The H2S comes with two trigger springs. The factory installed spring on the H2S is optimized for use with pistol caliber carbines. Using the H2S trigger on a rifle caliber?  Follow the included instructions to easily swap to our 3-3.5 pound green spring for the most solid wall and light break you have ever felt on a two stage trigger.
