The Timney replacement trigger for the SIG MPX 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.
The new Timney Trigger for the SIG MPX trigger is a 100% drop in replacement that features a hardened steel bridge to protect the trigger components from the vigorous bolt blow back charcteristics prominent in Pistol Caliber Carbines.
The single stage trigger features a non adjustable trigger pull weight of 3 pounds.
Drop in installation is simple once the SIG Factory trigger is removed, you will reuse the factory Hammer and Trigger pins. Set screws are located in the housing to lock the trigger in place and prevent the pins from walking out of place.
