Product Overview

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

One single-stage for every job — the Adaptable AR tunes from 2.5 to 5 lb (1.1–2.3 kg) without leaving the lower.

The TriggerTech Adaptable Single-Stage AR (flat, black) covers the full practical spectrum with external adjustability from 2.5 to 5 lb (1.1–2.3 kg): dial it down for a match weekend, up for cold-weather gloves, all without removing the trigger from the rifle. TriggerTech's Frictionless Release Technology is what the company credits for the clean break and ultra-short reset at every point in that range.

The flat shoe gives repeatable finger indexing and leverage. If your rifle wears more than one hat, this is the single-stage built for it.

Why shooters choose the Adaptable Flat

  • Externally adjustable 2.5–5 lb (1.1–2.3 kg) — retune in seconds, in the rifle
  • Frictionless Release break — consistent at every weight
  • Ultra-short tactile reset — fast, certain follow-ups
  • Flat shoe — consistent placement, added leverage

What the Adaptable Flat 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 flat shoe and adjustable weight suit a rifle used for both bench work and general range shooting. Confirm your pin size before ordering. Function-check the rifle before live fire.

Product Questions

Which receivers will the Adaptable single-stage fit?
It is a drop-in for AR-15 and M4 pattern lowers running mil-spec trigger pins. Check your pin size before ordering, since large-pin receivers are not compatible. Installation is a pin swap with hand tools, nothing more.
What does 'Adaptable' mean in the TriggerTech range?
The Adaptable models are the everyday-use tier, adjustable from 2.5 to 5 lb (1.1–2.3 kg) — a heavier, more practical window than the Diamond's match range. That makes them a sensible pick for a general-purpose rifle where you want a clean break but not a hair trigger. They share the same frictionless roller sear as the rest of the range.
How do I choose a setting within 2.5 to 5 lb (1.1–2.3 kg)?
Start at the heavier end and work down until the break feels controllable with the grip and gloves you actually use, rather than jumping straight to the lightest setting. Follow the instructions supplied with the trigger and function-check the rifle after any change. Written down, half a pound sounds small; on the range the difference is very noticeable.
Flat shoe or the curved Pro version?
This is the flat-shoe model, which many shooters prefer for a repeatable finger position and a straight rearward press. The Adaptable Pro curved is the same trigger with a curved face if that suits your hand better. Our AR-15 trigger guide explains how shoe shape affects feel.
How does delivery work?
It is dispatched from the United Kingdom with £5 tracked UK delivery in 7–10 business days, and tracking arrives by email when it ships. If a part turns out to be the wrong fit, see our returns policy or contact us and we'll help sort it.
