Timney Competition Trigger 668S - AR-15 Single-Stage 4 lb - Small Pin

The classic Timney Competition — a hand-calibrated 4 lb single-stage trigger that has anchored match ARs for decades.

The Timney Competition 668S drops a glass-crisp 4 lb single-stage pull into small-pin (.154 in) AR-15 lowers. Each unit is hand-calibrated in Phoenix: no creep, minimal overtravel and a break so repeatable it becomes part of your subconscious — exactly what deliberate match shooting demands. The 4 lb weight is the time-proven balance point: light enough for precision, deliberate enough for stages shot under adrenaline.

This is the trigger that introduced generations of AR shooters to what a proper break feels like, in a self-contained drop-in module that installs in minutes and holds its calibration for the life of the rifle.
