Product Overview

The Timney AR PRO is a self-contained drop-in two-stage trigger for AR-15 and M4 pattern rifles, fitting standard lower receivers through the existing trigger and hammer pin holes.

Timney's flagship two-stage trigger for the AR-15 — match take-up and a 1.5 lb (680 g) break in a sealed drop-in module.

The Timney AR PRO delivers a genuine two-stage match pull — 8 oz (225 g) of smooth first-stage travel into a crisp 1.5 lb (680 g) second-stage break — packaged in Timney's fully self-contained drop-in housing. No loose springs, no fiddly sear alignment: the calibrated module sits in the lower and pins in place, delivering the pull Timney's technicians hand-tested before it shipped.

For precision AR-15 builds — target rifles, varmint uppers, long-range gas guns and UK straight-pull builds — the AR PRO's two-stage discipline lets you prep the shot as the reticle settles and break it without disturbing the picture. It sits at the top of Timney's AR-15 line.

Why shooters choose the AR PRO

  • Two-stage match pull — 8 oz (225 g) take-up, 1.5 lb (680 g) break
  • Self-contained drop-in module — the calibrated pull, guaranteed
  • No creep, minimal overtravel — a genuinely match-room break
  • Hand-calibrated and tested — Timney has built triggers since 1946

What the AR PRO fits

Drops into AR-15/M4 pattern lower receivers using the existing trigger and hammer pin holes — among the easiest trigger installs there is. That includes UK straight-pull AR-15 builds, where a two-stage break is the most effective single change you can make to how the rifle shoots. The unit is self-contained, so confirm your trigger pin size before ordering. Function-check the rifle fully before live fire.

Product Questions

Does the AR PRO drop into any AR-15 lower?
It is a self-contained drop-in unit for AR-15/M4 pattern lower receivers. The one thing worth checking first is your trigger pin size, since AR lowers come in both small and large pin patterns. Measure or check your receiver's specification before ordering, and contact us if you are unsure.
How does the AR PRO differ from Timney's other AR triggers?
It is Timney's two-stage AR unit with an 8 oz (225 g) first stage and a 1.5 lb (680 g) second stage, which is a genuinely light competition-style pull. That is lighter than the brand's 3 lb (1.4 kg) and 4 lb (1.8 kg) single-stage AR triggers, and it is set at the factory rather than needing dialling in. It arrives as one sealed cassette rather than loose components.
What is the advantage of the self-contained cassette?
Everything is held in a housing, so the sear geometry is set before it leaves the factory and does not depend on how the parts settle in your particular lower. Fitting is a matter of removing the original trigger group and dropping the unit in place with the pins. Always function-check the rifle afterwards, and if anything feels wrong, stop and get it looked at.
Is a light two-stage the right choice for me?
If you shoot precision or slow-fire matches with an AR, the light first stage helps you set up the shot; for hard-use or field work many shooters prefer something heavier. Our AR-15 trigger guide walks through how pull weight and stage count affect the way a rifle shoots. Nothing additional needs buying to run it.
How is it delivered, and what if it doesn't fit?
The trigger goes out from the United Kingdom with £5 tracked UK delivery in 7–10 business days, and you'll receive tracking by email when it ships. If the pin size turns out to be wrong for your lower, see our returns policy or contact us and we'll help sort it.
