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.

Great mod to Mil-Spec triggers

by -

Had two ARs that had 7# trigger pulls (a Windham Weaponry & a standard Mil-Spec kit in a Striker Lower). Ordered the springs, shipped fast, and did a simply install. Both ARs now test out with 4# trigger pulls. Took the Mil-Spec hammer and bobbed it to look like the hammers on the JP and Anderson drop-in triggers, and the trigger pull down to 3.6#. On the range, I had no lite strikes or problems, and groups were tighter.

Definite Upgrade!

by

Installed these on a Spikes Battle Trigger and went from an average trigger pull of 7 lbs. to a smooth crisp 4.5 lb average trigger pull. Very Nice!

Had to try them

by -

Well worth the $10 , did a light polishing/smoothing on the trigger components and very happy with the improvement . Don't have a pull gauge but much lighter feel .

Best 10 bucks you will ever spend!

by

I'm sure just the springs make for a great upgrade. However, a polish plus this kit makes any trigger smooth as butter. I realise that sounds generic and overused but as soon as I pulled it for the first time "butter smooth" and "wow" were the first two things that popped into my mind. I'm still relatively new to building, so I was amazed and impressed at what this kit and a simple yet informative video from up on how to polish.
<br>Stock triggers still have a bit of travel as others have said but its incredible how much smoother and lighter this kit makes it.
<br>👍

Works great

Don't have a trigger weight gage to measure pull weight but the difference is very noticeable just using the trigger normally. Feels much Lighter immediately.Best 10 bucks spent on my new build

Cheap alternative to a drop in.

by -

Installed on a cmmg lower parts kit mil spec trigger in a poverty pony lower. The JP springs reduced the pull weight by a pound or more. I did polish the trigger before hand which slicked it up. There is a little take up almost like a two stage with a wall and then a clean break. It’s not my POF 3.5lb but I don’t not like it now.

Drastically reduce trigger pull as described!

by -

I purchased a couple sets to replace in Palmetto lowers in the Fall of 2017. These work amazing. The standard 7.5# trigger pull dropped to 4.75# in both lowers. I've ran a few hundred through the lowers with zero issues to date. Trigger pull remains in 4.75# range to date. I'm ordering more for other lower conversions. Excellent product and value.

Need to buy more of these

by -

Can't say whether or not it lowers the poundage of my stock trigger in my Ruger 556. But it shore made it feel 100 times better. Worth the ten bucks

Reduced trigger pull by 2 lbs.

by -

I recently installed a PSA EPT (Enhanced Polished Trigger) in my lower, replacing the OEM trigger. Still had a trigger pull of 6½ lbs, albeit very smooth and crisp. Today I installed the JP Enterprises enhanced reliability trigger kit. Trigger pull weight dropped to 4½ lbs. Still feels smooth and crisp, so I am very happy with it.

Make stock trigger perform better than ALG QMS

by

I am building 2 lowers. On one lower I paired JP Enhanced Reliability Springs with stock FCG with a little polishing. On the other lower I installed ALG QMS trigger. To my surprise the JP springs + stock FCG performs much much better: smooth pull and crisp break. You can hardly feel any take-up. The ALG QMS on the other hand is gritty with long take-up. Returned ALG QMS and buying more JP Springs.

Best BANG for your buck

by

I've now put these springs on ALL of my ARs. These Springs + a little polishing to the rest of your trigger components gives you fantastic results. of course PA with great price fast shipping.

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

perfect cure for .22 light strikes

by

I purchased this spring kit on a whim in hopes that my .22 trainer could be brought back to life after a spell of light primer strike FTF. The pull with GI trigger is very close in weight "almost negligible" but the round pops every time. Even loaded with rounds that has 2-3 light strikes from the stock setup they all went off.

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.

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.

Kit works better than ecpected!

by

The JP Enterprises AR-15 Enhanced spring kit is a great value. I am more than happy with the results. I would highly recommond this kit !

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.

Recent Purchase

by

Another outstanding experience dealing with PA! I will continue to use your company as long as ya'll continue to offer such outstanding service .

Simple and quick upgrade!

by

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.

Right on target

by

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

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

Looking for a cheap trigger job that works?

Just installed these in my lower. WOW! My trigger is so smooth and light now. Can't wait to see how it performs! Well worth the money!
