AR-15 – Drop-In Trigger – Diamond Single-Stage – Flat Shoe
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
TriggerTech’s Diamond single-stage flat trigger for the AR-15 is built for shooters who want top-shelf trigger feel, a brutally clean break, and real pull-weight adjustability without messing with springs and prayers. This drop-in unit uses TriggerTech’s zero-creep design and CLKR system to give your rifle a crisp single-stage press, extremely short overtravel, and a fast reset that feels like it has its life together.
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, oversized pins, or a non-standard cassette trigger setup.
What it does
This drop-in cassette trigger replaces the factory fire control group with a single-stage system designed to deliver a true zero-creep break, extremely short overtravel, and a sub-0.030 inch tactical reset. Pull weight is externally adjustable from 1.5 to 4.0 pounds in 2-ounce increments with the trigger installed.
Why it’s worth it
If you want one of the best AR-15 triggers TriggerTech makes before you start entering “my rifle costs more than my truck payment” territory, this is it. The Diamond line is for shooters chasing precision, consistency, and a press that feels sharp enough to make a mil-spec trigger feel like farm equipment.

Install notes
Install carefully, then verify proper safety function, hammer reset, and live-fire reliability before hard use. A trigger is not where you freestyle and hope the rifle shares your optimism.
Verify before you buy
Verify your lower is a standard AR-15 pattern lower with mil-spec pins and confirm you want the Diamond single-stage flat version, not the two-stage, curved, or AR-10 variant.
