The TriggerTech Duty Two-Stage is a two-stage drop-in trigger with a flat shoe for AR-15 and M4 pattern rifles.
Two-stage discipline, flat-shoe mechanics — the Duty Two-Stage Flat is the thinking shooter's hard-use trigger.
The TriggerTech Duty Two-Stage AR (flat) combines staged control at a robust weight with the flat shoe's modern advantages: repeatable finger indexing, better leverage and a straight-to-the-rear press. First-stage take-up flows smoothly to a wall that TriggerTech's Frictionless Release Technology is credited with keeping free of creep — the commitment point is a fact, not a feeling.
Sealed stainless internals and a fixed configuration mean the trigger you zeroed with is the trigger you keep. Drop-in fit, staged discipline, modern execution.
Drop-in fit for AR-15/M4 pattern lower receivers with standard Mil-Spec trigger pins, which includes UK straight-pull AR-15 builds — a flat shoe with a staged wall is a strong all-round choice for a straight-pull rifle used at the range and in the field. Confirm your pin size before ordering. Function-check the rifle before live fire.

£5 tracked UK delivery on every order via Royal Mail Tracked 24. Our products are ordered in from the manufacturer rather than held in UK stock, so please allow 7 to 10 business days (Monday to Friday, excluding bank holidays) from the date of your order for it to reach you. Tracking details are emailed on dispatch. UK delivery only.
You have 30 days from receiving your order to cancel it for any reason, then 14 days to send it back unused and in its original packaging. Faulty, damaged or incorrect items are replaced or refunded and we cover reasonable return postage. Refunds go back to your original payment method within 14 days of receiving the return.
It is a drop-in unit for AR-15/M4 pattern lower receivers with mil-spec trigger pins, replacing the standard fire control group without permanent modification. Check whether your lower is mil-spec or large pin before ordering. Everything else about the build stays as it is.
The two stages give you a take-up and a defined wall so you can settle the sights before the break, and the flat shoe keeps your finger contact in the same place while you do it. Together they suit shooters who want repeatable, deliberate shots from a rifle that still has to be handled hard. It is a noticeable step up from a standard mil-spec fire control group.
Duty is the set-weight, hard-use option, whereas the Competitive comes at a fixed competition weight and the Adaptable and Diamond models let you adjust the pull yourself. If you want to see how the brands and models line up before deciding, our <a href="/blogs/buying-guides/best-ar-trigger-brands-compared">comparison of AR trigger brands</a> is a good starting point. Fitment is the same across all of them.
A punch to drive the trigger pins out and back in, plus something to support the lower so you do not mar the finish, is all it takes. Keep the safety selector, grip and any detents to hand as you reassemble. Once fitted, function-check the rifle unloaded and confirm the safety operates correctly.
Dispatch is from the United Kingdom with £5 tracked UK delivery in 7–10 business days, and tracking is emailed to you when your order leaves us. If the part turns out to be the wrong fit, see our returns policy or <a href="/pages/contact">contact us</a> and we'll help sort it.
