Product Overview

The TriggerTech Diamond Two-Stage is an externally adjustable two-stage drop-in trigger with a flat shoe for AR-15 and M4 pattern rifles.

Two stages, no creep — the Diamond Two-Stage brings frictionless staged control to precision AR-15 shooting.

The TriggerTech Diamond Two-Stage AR applies Frictionless Release Technology to the two-stage format: a smooth, rolling first-stage take-up into a wall TriggerTech credits as free of creep, then a break that happens exactly where your finger learned it lives. Externally adjustable from 1.5 to 4 lb (0.7–1.8 kg) total, it covers everything from deliberate target work to faster staged shooting — and the reset remains signature TriggerTech: short, crisp, certain.

The flat shoe adds repeatable finger indexing and leverage, while sealed stainless internals mean the pull you tuned survives dust, rain and thousands of cycles.

Why shooters choose the Diamond Two-Stage

Frictionless two-stage pull — staged discipline with a clean wall
Externally adjustable 1.5–4 lb (0.7–1.8 kg) — tune both character and weight
Short, crisp reset — fast follow-ups from a staged trigger
Flat shoe — consistent placement and leverage

What the Diamond Two-Stage 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 — an adjustable two-stage is arguably the best match for a straight pull, since the rifle is shot deliberately and the staged wall rewards a settled sight picture. Confirm your pin size before ordering. Function-check the rifle before live fire.

Product Questions

Will this Diamond Two-Stage fit a standard AR-15 lower?

It is a drop-in fit for AR-15/M4 pattern lower receivers using mil-spec trigger pins, so it goes straight in where the standard fire control group came out. Confirm your lower uses mil-spec pins rather than large pins before ordering, as that is the usual compatibility question. No permanent modification to the receiver is involved.

What makes the Diamond different from the other TriggerTech AR triggers?

The Diamond is the top of the AR line here and gives the widest useful adjustment of the two-stage models, from 1.5 lb (680 g) up to 4.0 lb (1.8 kg) total. That range takes it from a light bench or precision setting right up to a general-purpose weight. Our AR-15 trigger guide walks through how to pick a weight to suit the way you shoot.

How light can I safely set it?

The unit is specified as adjustable between 1.5 lb (680 g) and 4.0 lb (1.8 kg), and you should stay inside that range rather than trying to force it lower. Very light settings suit deliberate slow fire from a rest; if the rifle is used for anything more dynamic, most shooters settle nearer the top of the range. Always function and safety check on an unloaded rifle after any adjustment.

Flat shoe or curved - which should I pick?

This is the flat-shoe version, which gives a straight-back pull and a consistent contact point regardless of how high your finger sits. Curved shoes feel more familiar to anyone coming off a standard mil-spec trigger. Fitment is identical either way, so it is purely a question of what your hand prefers - and nothing extra is needed to run it beyond your existing pins.

What is the delivery and returns position?

We send orders from the United Kingdom with free tracked UK delivery in 7–10 days, and tracking is emailed to you when it ships. If the trigger turns out to be the wrong fit for your lower, see our returns policy or contact us and we'll help sort it.
