Product Overview

The TriggerTech Diamond Pro is an externally adjustable single-stage drop-in trigger with a Pro Curved shoe for AR-15 and M4 pattern rifles.

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 and external 1.5–4 lb (0.7–1.8 kg) 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 moving off conventional triggers who want familiarity without compromise.

TriggerTech credits the free-rolling release for a pull that feels lighter than its measured weight and breaks the same press after press. Internals are sealed stainless — see the specification table below.

Why shooters choose the Diamond Pro AR

Frictionless Release break — the wall is the shot
Externally adjustable 1.5–4 lb (0.7–1.8 kg) — match to field weights on one unit
Pro Curved shoe — classic feel, self-centring geometry
Ultra-short tactile reset — speed without hunting

What the Diamond Pro AR fits

Drop-in fit for AR-15/M4 pattern lower receivers with standard Mil-Spec trigger pins, which includes UK straight-pull AR-15 builds — the adjustable range runs from a light 1.5 lb (680 g) bench weight up to a more deliberate 4 lb (1.8 kg), so one trigger covers target and general range use. Confirm your pin size before ordering. Function-check the rifle 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 (0.7–1.8 kg), 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.
