The Stern Defense H2S Hybrid 2-Stage Trigger is specifically designed for popular pistol-caliber carbines and is perfect for use in the AR platform. This innovative trigger blends dependable mil-spec trigger features with finely tuned competition trigger elements to create a versatile design for any user.

Replacing any OEM AR-15 trigger, the Stern Defense H2S Hybrid 2-Stage Trigger includes a 2-pound first stage and a 4-pound second stage that breaks cleanly. It also features a duty spring, which prevents inadvertent bump fires and protects against failures to reset, making the trigger a great choice for PCC triggers. Furthermore, the trigger has been tested in a 250,000-round torture test without experiencing a single failure, so the durability is ensured.

If you want to adjust the poundage, simply exchange the green, 3-pound spring included with the trigger, and you'll achieve a solid wall that breaks effortlessly. Installing this trigger is simple because it utilizes mil-spec trigger and hammer pins, and it has a semi-flat bow available with or without a nickel-boron coating. The trigger and disconnector are both machined from A2 tool-steel bar stock.

In summary, the Stern Defense H2S Hybrid 2-Stage Trigger is the perfect trigger for popular pistol-caliber carbines. It includes dependable mil-spec trigger features with finely tuned competition trigger elements to create a versatile trigger design that users can rely on.
