Details

Precision-calibrated springs produce a consistent pull on a stock JP M15 rifle trigger, while preserving ignition reliability with U.S.-manufactured ammunition. This trigger and hammer spring kit produces a 3.5 to 4 lb. trigger pull. These springs are designed to be optimal with JP Enterprises fire control groups but can also be used with properly prepared (instructions included) mil-spec trigger/hammer components to produce a 4- to 5-lb. pull with a smooth “roll off feel and good control. Install this spring kit in your AR-15 trigger group to ensure reliable primer strikes on hard military surplus ammo.


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 trigger spring, hammer spring, and disconnector spring
  • Suggested Use: Hobby / Sporting

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

Equipment should not be a limiting factor. Whether a professional or a first-time shooter, move up to the best. JP Enterprises creates innovative new ideas that fill the needs of serious and recreational shooters. Their policy is simple: if you are not happy, they are not happy.

This jp 3.5t spring i get just under 5lbs which is not really bad compare to my colt. I went target shooting yesterday and i used 3 different ammos the winchester, american eagle and tula. All of them went bang without single problem. I recommend this spring to anyone

Good Investment

by

Added these to my ACT ALG trigger and they made it even more enjoyable to shoot. Makes for a good combination. I will be adding more of these to some of my other FCGs. Shipping was very prompt as usual.

Huge step up from milspec

So far so good

I changed out the JP Reduced Power Spring kit (JPS3.5) to the JP Reliability Enhanced Spring kit (JPS3.5T) because I experienced a lot of light primer strikes with the JPS3.5 version with my AR15. Now that I replaced the spring kit with the JPS3.5T, I haven't experienced any light primer strikes with the recent change, thus far. The trigger feels real smooth. I would recommend this product.

Good product

by

I installed these springs with my ALG Defense ACT trigger kit. The result is a very crisp 4.5 pound trigger pull. I haven't had any light primer strikes as of yet. For the money you can't go wrong with these springs.

Great Springs

I recently ordered a bunch of parts to finish off my first AR build. Primary Arms sent me all of my products within 3 or 4 days of ordering. I even asked for some stickers to "decorate" my gun case and they sent a variety to help lol. Definitely recommend to everyone I know. Awesome company.
