The TriggerTech Adaptable Primary is an externally adjustable two-stage drop-in trigger for AR-15 and M4 pattern rifles, fitting Mil-Spec lower receivers.
The adaptable two-stage in show-stopping silver — wide-range adjustability with TriggerTech's Frictionless Release break.
The TriggerTech Adaptable Primary Two-Stage AR spans the practical spectrum: externally adjustable from 2.5 to 5 lb total, it tunes from a sharp practical-match weight to a deliberate heavier pull on the same unit. The release uses TriggerTech's Frictionless Release Technology, which the company credits for a wall free of creep and a break that feels the same at every setting, while the two-stage format gives you prep-and-commit discipline.
The silver-finished shoe distinguishes this variant on the rifle as clearly as the pull distinguishes it on the range. Internals are sealed stainless — see the specification table below.

Frequently Asked Questions
Which receivers does this Adaptable Primary two-stage fit?
It is a drop-in fit for AR-15 and M4 pattern lowers using mil-spec trigger pins. Large-pin receivers are not compatible, so check your pin size before ordering. Beyond that, no receiver work is needed — it goes in as a complete cassette.
What does TriggerTech's Frictionless Release mean in practice?
TriggerTech's mechanism uses a free-floating roller between the sear surfaces instead of two faces sliding across each other, which is why they describe it as zero creep. What you feel is a break with no perceptible movement or drag before the shot goes. It also stays consistent as the trigger gets used, since there is far less rubbing to wear surfaces in.
How do I set the pull weight?
This one is a two-stage trigger with tool-less adjustment from 2.5 to 5 lb, so you can change the weight without stripping the unit or hunting for an Allen wrench. Set it, then function-check the rifle thoroughly before use. Two-stage means you take up the first stage, hold at the wall, and press through a defined second stage to fire.
Why choose the silver finish version?
The finish is cosmetic rather than functional — this model comes in silver, and other trigger bodies in the range come in black, PVD black or stainless if you want a different look inside the receiver. Choose on the mechanism and pull weight first, then the color.
