Description:

For Smooth, Light Trigger Pull & Reliable Ignition
JPS3.5T produces 3.5 to 4 lb. trigger pull with JP Fire Control parts. This kit is intended for use with JP trigger parts and will not necessarily yield substantial change on standard AR-15 trigger components. Application: Use of this spring kit allows for use of ammunition with low-sensitivity primers such as those found in NATO-spec and various foreign-manufactured ammunitions, but in the case of large-frame ARs and duty/defense rifles, domestic-manufactured ammo is strongly recommended to ensure 100% ignition reliability. The JPS4.0 Tactical Spring kit will yield a 4.0-4.5 lb. trigger pull with JP Fire Control parts. This kit is intended for use with JP trigger parts and will not necessarily yield substantial change on standard AR-15 trigger components produces a 4 to 4.5 lb. trigger pull.

JPS3.5T Enhanced Reliability Spring Kit

SPECS: Spring steel. Kit includes red-coded hammer spring, yellow-coded trigger return spring, and disconnector spring. For use on AR-style .308 rifles; not for defense or duty applications.

Definitely recommended

Brownells USA Works well with stock triggers 09/03/2018

Using just the hammer spring brought my stock trigger’s pull down from 8lbs. to 5-5 1/2 lbs. with a consistent break. Using the JP trigger and disconnector springs brought the trigger pull down to about 4 1/2 lbs. but the break wasn’t as “distinct” for me, so I went back to the stock trigger and disconnector springs. No FTF’s so far after shooting 200 rounds of various ammo ranging from match to duty to foreign surplus. This product exceeded my expectations.

Slightly recommend

Brownells USA Doesn’t help with a stock trigger 24/02/2018

Found out the hard way these won,t change a thing with a stock mil spec trigger. These look to have the exact same hammer spring as mil spec. Bottom line I had the exact same 8 lb. trigger pull after installing these. Do yourself a favor and get the 3.5 version if you want a reduced trigger pull weight. Just make sure to test the reliability with all the ammo you use.
