AR-15 – Drop-In Trigger – Duty Two-Stage – Flat Shoe – 3.5 lb
PLEASE DOUBLE CHECK DETAILS AND FITMENT BEFORE PURCHASE.
TriggerTech’s Duty two-stage flat trigger for the AR-15 is built for shooters who want a more hard-use-minded trigger with a cleaner break than stock and none of the mushy surplus nonsense. This drop-in unit uses TriggerTech’s zero-creep design with a longer first stage and a more forceful reset than the lighter competition lines, making it a better fit for serious-use rifles that still deserve a proper trigger.
Fitment
Fits AR-15 pattern rifles using standard mil-spec trigger pin dimensions.
Does NOT fit
Verify compatibility before purchase if your lower uses proprietary trigger geometry, oversized pins, or a non-standard cassette trigger setup. This listing is for the AR-15 version, not the AR-9 or AR-10 Duty variants.
What it does
This drop-in cassette trigger replaces the factory fire control group with a two-stage system designed for a fixed 3.5 lb pull, zero creep, and a stronger reset feel suited to defensive, training, and general-purpose rifle use.
Why it’s worth it
If the Diamond is the race car and the Competitive is the sports sedan, the Duty is the truck that still moves with purpose. It gives you a cleaner trigger press than mil-spec junk while keeping a more deliberate feel for serious-use rifles.

Install notes
Install carefully, verify proper safety function, hammer reset, and reliable live-fire performance before hard use. A trigger is not a “we’ll see what happens” part.
Verify before you buy
Verify your lower is a standard AR-15 pattern lower with mil-spec pins and confirm you want the Duty two-stage flat version, not the single-stage, curved, or AR-9/AR-10 variants.
