JP Fire Control Kit

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.
