TriggerTech Adaptable Primary Two-Stage Flat Trigger for AR-15, 2.50-5 lbs Draw Weight, Right-Handed

The TriggerTech Adaptable Primary Two-Stage Flat Trigger for AR-15 is a precision drop-in trigger built for shooters who demand consistency and control across every application—from 3-gun competition and tactical training to long-range hunting and precision rifle work. This right-handed trigger combines the familiar short two-stage feel of a 1911 with modern AR engineering, delivering a crisp break with zero creep and sub-0.030" reset that rewards good trigger discipline on every shot.

What sets the Adaptable Primary apart is its frictionless release technology (FLTWR) and CLKR pull-weight adjustment system. You can dial your draw weight from 2.50 to 5 lbs using a set screw without removing the trigger, and the hammer strike force stays constant—meaning reliable primer ignition regardless of your setting. Because there's no friction-based engagement, the trigger maintains shot-to-shot consistency that actually improves over thousands of rounds, not degrades. The 440C stainless steel internals resist corrosion, and the 7075 aluminum housing with PVD black coating handles hard use without complaint.

Installation requires detail-stripping your lower receiver; TriggerTech recommends having a professional gunsmith handle the job if you're not comfortable with full disassembly and function-checking. Once in, you'll notice that many shooters report the pull weight feeling roughly half a pound lighter than traditional triggers at the same measured force—a real advantage when you're pushing for accuracy under pressure. Whether you're running a duty rifle, competition gun, or hunting platform, this trigger grows with your skills and shooting style.

Frequently Asked Questions

Can I adjust the pull weight without removing the trigger?

Yes. The CLKR adjustment system lets you change the pull weight in 2 oz increments using a set screw while the trigger is installed in your lower receiver. This means you can fine-tune your feel at the range without detail-stripping.

Does the hammer strike force change when I adjust the pull weight?

No. The Adaptable Primary maintains constant hammer strike force across all pull-weight settings, so you'll get reliable primer ignition whether you're running 2.50 or 5 lbs. This is what "adaptable" means in the design—your settings adapt to you, not the other way around.

What do I need to install this trigger?

You'll need the ability to fully detail-strip your AR-15 lower receiver and reassemble it correctly. TriggerTech's installation guide is written for experienced gunsmiths. If you're not comfortable disassembling and function-checking your lower, we strongly recommend having a professional gunsmith install and verify the trigger before shooting.

Are trigger pins included?

No. The trigger pins are not included; you'll need standard mil-spec pins (0.154") to install this trigger.
