681-ST : AR PCC SINGLE STAGE, STRAIGHT **2.5-3lb** Fits all calibers in PCC (.40, .45, 9mm)

The Timney replacement trigger for the SIG MPX carbine rifle is the latest in the Timney lineage of AR-style, semi-automatic, replacement triggers.  Timney is offering four models for the MPX - single-stage, two-stage and curved and straight shoe options for each model.

The trigger, hammer, and bridge are constructed of heat-treated steel.  The housing is machined 6061, T6 anodized alloy and the trigger is factory calibrated for a pull weight of three-pounds for the single stage and a two-pound first stage and two-pound second stage for the two-stage model.

Both triggers are a self-contained, 100% drop-in trigger ready to install in your rifle for an exceptionally smooth, crisp, trigger pull with no gunsmithing, fitting, or adjusting required.
