H2S Hybrid 2 Stage - Drop in Trigger



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 high speed low drag competition triggers. 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.  With our duty spring in place, long gone are the days of inadvertent bump fires and failure to reset concerns so common in the PCC market when using a drop in trigger.   Using our trigger on a rifle caliber? Want to step down the poundage?  Follow the included instructions to easily swap to our 3 pound green spring for the most solid wall and light break you have ever felt on a two stage trigger.



  •  Standard mil-spec pin size
  •  Use for AR15 and AR10
  •  6061 billet housing
  •  Trigger and disconnect machined from A2 tool steel bar stock.
  •  Hammer machined from  S7 shock resistant steel bar stock.
  •  Semi flat trigger bow
  •  Cold Nitride Finish



Stern Defense does not recommend the use of our green spring or other light poundage short reset triggers on pistol caliber carbines due to the reciprocating mass.  Please use our factory preinstalled spring on the H2S for use with pistol caliber carbines.

    This drop-in trigger is not only easy to install but also one of the cleanest braking trigger I’ve felt. Cannot wait to see what other products stern defense will be releasing!
