Product Overview

Diamond performance through TriggerTech's signature Pro Curved shoe — adjustable, frictionless and instantly familiar.

The TriggerTech Diamond Pro AR pairs the flagship Diamond internals — Frictionless Release Technology with a genuine zero-creep break and external 1.5–4 lb adjustability — with the Pro Curved shoe, TriggerTech's refined take on the traditional curve. The gentle radius guides the finger pad to centre naturally while retaining classic feel, making it the pick for shooters transitioning from conventional triggers who want familiarity without compromise.

The free-rolling release means the pull feels lighter than its measured weight and breaks identically press after press, while sealed stainless internals hold that consistency through weather and round count alike.

Why shooters choose the Diamond Pro AR

Frictionless zero-creep break — the wall is the shot
Externally adjustable 1.5–4 lb — match to duty weights on one unit
Pro Curved shoe — classic feel, self-centring geometry
Ultra-short tactile reset — speed without hunting
Sealed stainless internals — all-conditions consistency

Fit & installation

Drop-in fit for AR15/M4-pattern lowers with standard Mil-Spec pins; function-check before live fire.

Product Questions

Does the Diamond Pro fit standard AR-15 lowers?

Yes, it drops into AR-15 and M4 pattern receivers using mil-spec trigger pins and needs no machining. As always with drop-in triggers, confirm pin size before ordering. It installs as a single cassette rather than separate trigger and hammer parts.

What is the 'Pro Curved' shoe about?

It is TriggerTech's curved trigger face, shaped for shooters who prefer the traditional AR profile over a flat bow. The curve tends to centre your finger naturally, which some people find quicker to pick up under time pressure. Mechanically it is identical to the flat-shoe Diamond — the difference is only where and how your finger sits.

How light can I set it?

The Diamond adjusts tool-lessly between 1.5 and 4 lb, giving you a genuine match weight at the bottom and a practical one at the top. The frictionless roller sear means the release stays clean across that range rather than getting mushy when you go light. Function-check the rifle after every adjustment.

Should I buy this or the flat-shoe Diamond?

Buy on shoe shape alone: this curved version if your muscle memory is built on standard AR triggers, or the flat-shoe Diamond if you want a fixed contact point for precision work. Both come in the same Blue/Black finish and the same weight range. There is more of the line in the TriggerTech collection.
