Product description

Consistent 3.5 lb. Trigger Pull On A Stock JP M15 Rifle Trigger

The JP Enterprises 3.5lb Enhanced Reliability Trigger Spring Kit is specifically designed to be optimal with the JP Enterprises fire control groups but can also be used with properly prepared mil-spec trigger/hammer components to produce a 4- to 5-lb. pull with a smooth “roll-off” feel and good control.

This spring kit will produce a consistent 3.5 lb. trigger pull on a stock JP M15 rifle trigger while also preserving ignition reliability with U.S.-manufactured ammunition.

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.

This easy-to-install upgrade is an excellent way to improve the reliability and trigger pull weight of your AR-15 without spending a large amount of money.

Includes trigger, hammer, disconnector spring, and complete instructions on how to prep your parts for the best results.

Features:

  • 3.5 – 4 lb trigger pull on JP M15 AR trigger
  • 4 – 5 lb trigger pull on Mil-Spec trigger
  • Reliably ignites ammo with hard primers
  • Instructions included

Includes:

  • 1x Yellow JP Trigger Spring
  • 1x Red JP Hammer Spring
  • 1x JP Disconnector Spring

These spring kits are amazing, they take a gritty and heavy pull milspec trigger and make it better.
Dave Verified buyer
I have been building ARs for over 50 years and always used complete trigger systems for lighter pull weight. On a whim I tried this kit and was extremely surprised. It works great!! I’ll definitely be ordering more.

Have not used them, bought them as a spare, but I do like other JE products
Luke Verified buyer
Paired this with the AT3 Nickel Teflon 6lb flat trigger, and got the advertised 4 lb pull. Seeing the slight bit of overtravel others have mentioned, but its short and smooth.
Edwin Verified buyer
Works Perfectly.

I highly recommend this JP product because it works flawlessly.

I bought a two-stage trigger, and the pins were shifting with each shot. I followed Alvin's recommendations and bought the two recommended items, and everything works perfectly. The guys at AT3 Tactical provide excellent service and quality.

Always said if it’s not broke don’t fix it, but I want a little smoother trigger without spending more money than I need [link removed] I chose a spring kit . An the difference is night and day . Absolutely love it. My so got his first rifle and he shot both and now he’s gonna change out his trigger springs. Thank AT3 👍

Great product at a great price point. Good trigger up grade for those of us on a budget! Easy installation with good instructions. Just wish it came with a litter sear grease!
nathan.mckenzie Verified buyer
They work well, a crisper brake on both my mil spec triggers. Fired well at the range, no issues with light primer strikes.
