JP Reduced power spring kit, yields about 4 to 4.5 lb pull with standard AR-15 trigger parts and 3.0 to 3.5 lbs with JP trigger parts.

Note: Use of this spring kit requires the use of US-manufactured (domestic) ammunition or reloads with domestic (non-NATO spec) primers as ignition reliability will be reduced with hard, low-sensitivity primers such as those found in foreign-manufactured ammunitions and NATO-spec ammunition. Use these parts only in rifles for recreational or competition shooting. Do not use this spring kit for any defense or duty applications or any AR-10 type rifle.
