The Griffin Armament adjustable 2-stage AR trigger is a Milazzo-Krieger style match trigger for AR-15 lowers (Griffin part no. GATSATS). Griffin Armament builds it in Watertown, Wisconsin from a case-hardened mil-spec 8620 steel trigger, a 440C stainless disconnector and a lightened 440C speed hammer with a nickel-Teflon coating. It leaves the factory pre-adjusted, but overtravel and disconnector engagement can both be tuned if your lower is toleranced differently or you want a different feel. Hammer and trigger springs, two dimpled trigger pins, an Allen wrench and a manual come in the box. It is a straightforward way to give a carbine or precision AR a cleaner, more predictable break.

Key Specifications

• The trigger is a two-stage, Milazzo-Krieger style design, giving a defined take-up before a crisp break.
• The trigger itself is mil-spec 8620 steel at 62RC, case hardened for wear resistance.
• The disconnector is 440C tool stainless at 53RC, chosen for durability at the engagement surfaces.
• The hammer is a lightened 440C speed hammer with a nickel-Teflon coating for faster lock time and smooth cycling.
• Overtravel and disconnector engagement are adjustable, so the trigger can be tuned to your lower.
• It comes pre-adjusted from the factory, so most installs need no adjustment at all.
• A 5.5 lb trigger spring and hammer spring are included, along with two dimpled trigger pins and an Allen wrench.

Frequently Asked Questions

Does it work in a 9mm AR? Griffin warns that the two-stage trigger should not be used with 9mm Colt-style carriers that lack a ramp on the hammer-interfacing surface of the bolt carrier, as that can lead to a loss of intended function.

Do I need to adjust it after installation? Usually not. Griffin pre-adjusts it at the factory; overtravel and disconnector engagement are adjustable if your lower is toleranced differently or you want to refine the feel.

What comes in the box? The trigger, disconnector and speed hammer, an adjustment Allen wrench, one hammer spring, one 5.5 lb trigger spring, two dimpled trigger pins and a manual.
