TIMNEY TRIG FITS AR15 4LBS (SOLID)

Description

Timney’s drop-in trigger module for the AR-15 is built for shooters who want a meaningful upgrade over a mil-spec trigger without sending the lower to a gunsmith. The housing drops straight into any mil-spec small-pin lower — the same standard pin size used across the vast majority of AR-15 platforms — and the entire assembly self-contained, so there is no stacking of individual components, no fitting, and no adjustment required before the rifle goes back together.

The four-pound pull is factory set and non-adjustable, which is a deliberate trade-off: a fixed pull weight means the trigger ships with its geometry already dialed in and stays that way under sustained use. The break is single-stage with no intentional take-up before the wall, so what you feel is a consistent resistance followed by a clean release rather than a staged two-step sequence. That characteristic suits both deliberate precision work at the range and the kind of faster, index-heavy shooting common in action disciplines.

The hammer is machined from S7 tool steel, a grade chosen for its toughness under repeated impact, while the remaining components use A2 tool steel. Engagement surfaces are precision ground rather than cast or sintered, which directly affects how the break feels and how consistently it reproduces from shot to shot. An integrated anti-rotation and anti-walk pin system keeps the trigger pins fixed within the housing, eliminating a common source of long-term dimensional creep in AR trigger groups. Timney manufactures this trigger in the United States and backs it with a lifetime warranty.
