JP EZ Trigger Fire Control Package with Armageddon Gear Revolution Roller Trigger
.154 Small Pin Receivers
Along with the Revolution Trigger, this fire control package includes the JP Speed Hammer for reduced lock time and the adjustable, JP Adjustable/Reversible Safety Selector ensuring perfect safety function regardless of hole position in your lower receiver and also JP Anti-Walk Pins for a precise relationship between the fire control components. The result is a match-level release that breaks like the proverbial glass rod at about 3.5 lbs. (or greater, depending on your requirements and spring selection).
Spring Selection Guide:
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.
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.
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.
