Original JP Fire Control Kit

This kit for .154 small pin receivers consists of a JP trigger with engagement and overtravel screws and disconnector spring installed as an assembly, disconnector, instructional video, and our standard array of springs: yellow reduced power trigger spring both yellow and red reduced power hammer springs.

Spring Selection Guide:

• Competition/Recreation The yellow/yellow combination may be used for competition and various recreational applications with hand loads or domestic-manufactured, non-military ammunition.  It will result in a release weight in the 3.0-3.5 lb. range on most receivers. 
• Enhanced Ignition Reliability The yellow trigger spring combined with the red hammer spring will yield a release weight of 3.5-4.0 lbs. on most receivers and offers increased reliability for (5.56 NATO) or foreign-manufactured ammo with low sensitivity primers. The yellow-red springs must be used for any large-frame AR installation to ensure 100% ignition reliability.  This is also the minimum acceptable combination for tactical duty (LE) installations and should be used only with domestic-manufactured ammo in this application.
• Duty/Defense The tactical spring set includes a full powers (grey) hammer spring (purchased separately) and yellow trigger spring.  It may be required for agencies that mandate a trigger release weight of over 4 lbs.  This set up also insures 100% ignition reliability on both AR-15 and AR-10 type rifles.
• CMP To meet NRA Service Rifle Competition rules of a 4.5 lb. release weight, the CMP spring set (purchased separately) includes the full-power hammer spring and a custom trigger return spring, which will allow you to tune to a release weight just over 4.5 pounds to lift the NRA weights.
