Timney 661S AR-15 Skeletonized Trigger 3lb

Timney 661S Competition Trigger for AR-15

The Timney 661S represents the pinnacle of trigger craftsmanship for the modern AR-15 platform. This is a purpose-built competition trigger that transforms your rifle's performance with a clean, predictable break.

Key Features

• 3-pound pull weight — Light enough for precision shooting, heavy enough for safe handling
• Single-stage design — No creep, no surprises; just a smooth, crisp break
• Skeletonized construction — Lightweight aluminum alloy housing reduces reciprocating mass
• Small pin compatible — Fits standard AR-15 small-pin lower receivers
• Wire-EDM machined components — Hammer forged from S7 tool steel; trigger from A2 tool steel for durability
• Self-contained module — Installs using your rifle's original pins; no gunsmithing required
• Captive design — All components remain secure; eliminates pin rotation and walkout
• Hand-tested and calibrated — Each trigger is individually inspected for consistency

Installation and Use

This is a drop-in trigger module that requires no adjustments. Simply remove your factory trigger group and install the Timney using your existing hammer and trigger pins. The proprietary design prevents the common problem of pin migration that plagues some AR triggers.

Note: If your lower receiver is polymer, place a thin aluminum shim underneath the trigger to protect the material from stress concentration.

The Difference

Timney triggers deliver the kind of performance you'd expect from a precision bolt-action rifle, but in your AR platform. The feel is smooth, the break is crisp, and the reset is audible—giving you confidence in every shot.
