JP trigger springs

[patriot07]

Not "new" to the AR-15 world, but I just bought my first one in years after having owned a couple 10 years ago and selling them and staying out of the semi auto game ever since.

Got a Ruger AR 556 for cheap and looking to do a moderate trigger adjustment on a tight budget, and was told the JP springs and set screw were a good option. Has anyone installed the JP yellow spring kit and if so, did you get good trigger improvement and good reliability? I really don't want to permanently modify any components, but I've read in several places where you need to bob the hammer to get good results. Is that accurate?

I cannot speak directly to the JP yellow spring, but I can say that JP makes/sells/markets good products. But, I would not modify any components within an ar15. This is what I would do with the advice about bobbing the hammer. Ignore it. Unfriend that person on Facebook. Whatever forum you found that, put those posters on ignore. Take those people off your Christmas card list. If you decide you need to change any internal components, replace them, do not modify them.

I installed several yellow JP trigger springs on several AR's. Had varying success on trigger pull. Wasn't happy so replaced all but one with Geissele's. The one that really worked out well was on an LMTMWS.

You guys do Know you have to Tune the Springs Right??? You just don't drop them in and call it a day.

I have recommended and installed for folks dozens of JP springs and most often with ALG defense triggers. It is one of the best 75 I parts and 15 minutes of time that will greatly enhance usability of the platform. Once done I have not heard a single person say anything negative except wishing they had done it long ago

Over 2 dozen triggers I have modded with them and it has brought down the trigger pull to about 3.5#. You will have light primer strikes if running a harder prime round (russian)... pass that, with a little polishing works like a charm.

I have not heard or seen this anywhere before now...what do you do to tune them?

You have to bend the trigger and hammer springs, if you want a smoother lighter pull, bend the legs of the Trigger Springs upwards. And the same for the hammer spring, sometimes they will need a little tweaking to make sure all contact points are receiving the same, and even pressure. Other then that just Oil and Grease the proper areas.

I believe Bill Geissele has a video on YouTube showing you guys how to do this. And the Guys at JP will talk you through it.

Do you have a link? Are you sure you aren't talking about the buffer spring? I did some more googling (and I'm a google search guru) and could not find anything on this...

You're fucking killing me Smalls...


I'm not gonna watch it for you but I believe it's in this video.

If not just call and talk to Geissele or JP they will walk you through it. I talked to Bill personally and that's how I learned.

I can take just about any trigger and make it feel like a match grade trigger but I also have the tools and proper Jigs for the work. But adjusting the first and second pull weights via the trigger/Hammer Springs is just basic work it's really easy.

Also when I bought my first JP match trigger kit, one of the first Generations where you actually had to file and rework The Sear for proper fitment it came with a DVD that taught me so much about trigger work if you can get your hands on one of those DVDs it is awesome. It even contained information that I'm not even sure was legal to put out to the General Public as far as full auto operation.

Cool, thanks!

I may be late on this, but I consistently had light primer strikes on Winchester and CCI primers, as well as factory .223 ammo. In my opinion, go get a CMC trigger. They are regularly on sale for just over $100 and are better than most Geiselles I have felt, except for my SSA-E.

Thanks for the post. I should have been more clear up front that this rifle is not going to be any sort of precision gun. I may not even scope it at all. I just hate the mil spec trigger and I'm looking to spend $30 or less to improve it. I'm not at the point where I'm willing to pay $50 or more to improve anything on this gun. Honestly, I may not even shoot it at all. But if I do, that crummy mil spec trigger isn't worth dealing with.

But it's good to know that the JP springs didn't work for you. Did you bob the hammer or just pull them out?

If thats the case, it may be worth playing with them, but I have had better luck taking 1500+ grit sandpaper and polishing the contact surfaces in the trigger. I do it lightly first, then put a drop of an oil (CLP works) on the sandpaper to do a final pass. It will certainly take any get out, although the pull will still be long. Your perception of the pull is going to be a lot more positive though.

Didnt bob the hammer, more work than I wanted to do. Just slapped a CM in there.

 

[patriot07]

I've got a 1000 grit knife sharpening stone and was planning on polishing up the contact surfaces when I add the springs and set screw.

I might just try the set screw and polishing first and see how that goes. Personally, I dislike creep more than pull weight, so the springs might not even be necessary.
