AR-15 – Drop-In Trigger – Diamond Two-Stage – Flat Shoe
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
TriggerTech’s Diamond two-stage drop-in trigger for the AR-15 is built for shooters who want a light, adjustable break, a brutally clean wall, and a reset that feels sharp without feeling sloppy. This is a premium competition-minded trigger with a flat shoe and TriggerTech’s zero-creep design, made for shooters who want precision without tuning nonsense.
Fitment
Fits AR-15 pattern rifles using standard mil-spec trigger pin dimensions.
Does NOT fit
Not for AR-10-specific lowers. Verify compatibility before purchase if your lower uses proprietary trigger geometry, non-standard pin sizing, or a cassette-incompatible setup.
What it does
This drop-in cassette trigger replaces the factory fire control group with a two-stage system designed for a very clean break, minimal overtravel, and a short tactical reset. Pull weight is externally adjustable in fine increments without removing the trigger from the rifle.
Why it’s worth it
A cheap trigger makes a rifle feel like a screen door with commitment issues. The Diamond is the opposite. It is for shooters chasing precision, consistency, and a trigger press that feels expensive because, well, it is.

Install notes
Install carefully, verify proper safety function, hammer reset, and live-fire reliability before hard use. A trigger is not the part to “good enough” your way through while half paying attention.
Verify before you buy
Verify your lower is a standard AR-15 pattern lower with mil-spec pins and confirm you want the Diamond two-stage flat trigger, not a single-stage, curved, or AR-10 version.
