The TriggerTech Diamond is an externally adjustable single-stage drop-in trigger with a flat shoe for AR-15 and M4 pattern rifles.
The trigger that took on creep — TriggerTech's Diamond puts a frictionless 1.5–4 lb break in your AR-15.
The TriggerTech Diamond AR (flat) is built on Frictionless Release Technology: a patented free-rolling component between sear and trigger that removes the sliding friction a conventional trigger drags through. TriggerTech credits it for a break with no perceptible creep — the wall is the shot — plus an ultra-short, tactile reset and a pull that feels lighter than its gauge weight. The Diamond adds precise external adjustability from 1.5 to 4 lb without removing the trigger from the lower.
Stainless internals in a sealed housing keep the mechanism consistent through dust and rain. The flat shoe indexes your finger identically every press — a pairing precision AR-15 shooters have made a fixture on the line.

Frequently Asked Questions
Which lowers is the Diamond compatible with?
It is a drop-in unit for AR-15 and M4 pattern lowers with mil-spec trigger pins, fitted as one sealed cassette. Confirm your receiver's pin size before ordering. No permanent alteration to the lower is involved.
What separates the Diamond from the rest of the TriggerTech range?
The Diamond is the precision end of the line, with tool-less adjustment from 1.5 to 4 lb — a lighter window than the Adaptable models offer. That takes it into genuine match territory while still allowing a sensible working weight if you want one. It uses the same frictionless roller sear as the rest of the range, so the break is free of creep at any setting.
How does the tool-less adjustment work?
You change the weight on the unit itself without stripping it down or fishing for hex keys, which makes it practical to try a couple of settings at the range rather than committing at the bench. After any change, run a full function check before shooting. If you settle on the lightest end of the range, treat the rifle accordingly.
Flat or Pro Curved shoe?
This is the flat-shoe version, which gives a consistent contact point and a slightly straighter rearward press — the usual choice for precision and competition. The Diamond Pro curved is the same trigger with a curved shoe if you prefer a traditional AR feel.
