Timney AR PRO Two-Stage Trigger - AR-15 Drop-In (8 oz / 1.5 lb)

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.
