JP Trigger Replacement Kit
This M4 Replacement Kit includes the Revolution trigger along with a selection of optional springs to achieve a variety of release weights depending on your application. The combination of our unique trigger with its improved sear geometry and the roller trigger, this kit is an ideal drop-in trigger for any M4 or AR-type rifle. At a price much lower than any other trigger solution, this kit alone has been shown to yield a smooth roll-off feel that allows for consistent shot placement when accuracy is required.
The springs included with this kit include the yellow hammer and trigger springs, which may be used for competition and recreational applications with hand loads or domestic made non-military ammunition. The yellow/yellow combination results in a release weight in the 3.0-3.5 lb range on most receivers. Also included is the red hammer spring for use with military (5.56 NATO) or foreign-manufactured ammo with low-sensitivity primers. The red hammer spring MUST be used on any tactical duty (LE) installations and any AR-10 type installation for 100% ignition reliability. The yellow/red combination results in a release weight of 3.5-4.0 lbs on most receivers.
This replacement kit is for standard AR triggers. It has no adjustable features and so is not suitable to replace any existing JP adjustable triggers—standard or EZ.
As a drop-in replacement, this trigger will not yield a match-grade trigger setup. Choose the JPFCP-1EZ-R instead.
