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

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.

So far so good

by

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.

Primary Arms is the bees knees

by

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.

Smooth Trigger Pull

by

I used this spring set with the Spikes Tactical trigger to replace my old mil-spec trigger. What a difference 10-minutes made. It breaks like glass now, with no creep like in the old setup. Cant wait to get out to the range!Thanks Primary!

The ultimate trigger spring set

by

If you have a regular mil spec trigger in your rifle, this spring set will make a huge difference. This spring set along with a polish job on my PSA mil spec trigger went from an 8 pound pull down to 3 pounds. I highly recommend them

Trigger Job

by

Just came back from the range. After polishing all the contact surfaces with an Arkansas hard stone and installing the trigger springs on my new build, I'd say the mil-spec trigger has a pull between 4 to 6 lbs. No mis-fires, No FTE, and No FTF. I couldn't be happier. Ordered on Sunday on my front porch Wednesday night.

These enhanced ignition springs ignite the hardest of military primers while keeping trigger weight down.

Simple and quick upgrade!

Used these to replace the ones that came with Daniel Defense lower parts kit. Soft and smooth. Just right (without trigger job). Purchased another set for current build.

An Easy Tune Up

by

For a cheap price these springs make my standard trigger feel better than my friend's ALG. Definitely worth a thought if you aren't looking for a high end trigger.

Enhanced spring set

by

Excellent spring set to pair with a polished fire control group. The spring set greatly reduces the tension of the hammer on the trigger resulting in a much lighter trigger pull.

These springs are great!!

by

These springs are great for someone looking for a much smoother trigger pull with mil-spec lower components and for the price cant be beat especially if you don't want to fork over the $100-$200 for a drop-in trigger I've since put these springs in all of the rifles i own
