Default JP yellow springs for stock trigger

Hey everyone so I've been contemplating on getting the new jp yellow springs for the 15-22 trigger but wanted to get some opinions and see if some of you had them installed and what your experience is with them. With the reduced lbs or lb, is there a concern for light primer strikes? Is polishing necessary?

Default JP yellow springs for stock trigger

The yellow reduced power springs did not provide enough energy to the hammer to reliably ignite the round in my 15-22. I switched back to the OEM spring, and polished the trigger contact points.

jaPes...while using the oem springs and polishing the contact points.
how much of a difference did that make for you?

Default JP yellow springs for stock trigger

I swapped to the yellow springs, polished everything and added the set screw to eliminate creep. It smooth and crisp now, no sponginess or light strikes yet. But I've only put 200-300 rounds through the rifle since I did the work.

I have them installed, but I also installed the speed hammer and polished everything. Made a huge difference. I didnt have a guage but it was noticeable to me just on feel.

Default JP yellow springs for stock trigger

I would ONLY put in the trigger spring.
I put in the hammer spring and was getting a lot of light strikes. Put the OEM hammer spring back in and now works fine.

I had really good luck with the JP yellow springs for awhile, then I started to get some light strikes on the primers. I cleaned up the bolt a bit and it got better, but I think I'm going to put the factory hammer spring back in but leave the trigger spring and see how it goes. Once it gets a bit dirty I'll put the JP spring back in and see if starts failing again.

I switched to the yellow springs on three weapons. No problems at all and my groups are now half the size as they were with the factory springs.

I'm one of the nay-sayers on them. Reduced the trigger pull less than one pound on my 15-22. and that's a measured figure, not a guess. I put them in my grandson's rifle and had essentially the same results - not worth the expense or effort, IMHO.

Both triggers were originally in the 6 lb range.

I've had them in mine, along with the set screw mod, for over a year. I don't have the ability to test the pull weight of the trigger, but I felt like between these 2 steps I made a noticeable difference in the trigger feel. I have a Geissele SSA-E in my rifle's big brother, so I have some exposure to great triggers, and I still really like the stock trigger in my 15-22.

Put them in mine yesterday and had no problems through about 200 rounds. Some of them were fired, shall we say, very quickly.

Gonna take some getting use to, but that's the only mod I've made to mine to accommodate the "other modification." I think once I get use to it, it may very well be all I need to do, despite all the things I've read were necessary.

Yellow springs, Flitz, and a night of working the trigger with the upper off makes for a good cheap trigger job.

I just installed some yellow JP springs in my 15-22PC model. Not sure if the results will be the same since the factory trigger is different on the PC model. If I have light hammer strikes.. then I'll just put the hammer spring back in. Going to test it out this weekend.

alright fellas the springs are on their way. I decided for the price to give them a shot. I can always revert back to oem if need be.

The cost is low enough that it's worth a shot, but I wasn't really impressed. The problem with the stock trigger isn't necessarily weight, it's grittiness and creep. The spring might make it a little less gritty, but it made the creep worse on mine. Where before, when you finally got the trigger moving, it would break, now it the lowered pressure between the surfaces allows you to gradually move the trigger until it fires. It's lighter, sure, but I preferred it heavier but crisper.

Polishing with some flitz makes a big difference though.

Just an FYI I mic'd the yellow JP trigger spring and it is identical to the stock trigger spring. I left the stock trigger spring and disconnector spring in my 15-22. The stock disconnector spring is lighter than the JP. The only spring in the kit that is lighter is the hammer spring, which I swapped out.

Take it for what it worth.

Did the yellow springs, polished with a dremel & flitz, used moly on trigger face. Did my 15-22 and my sig sauer m400. Both triggers work great. Also did set screw on 15-22. Best $20. I have spent in a long time.

You won't regret it. And if for some reason you FTF your only out $10 and its not hard to put the blue spring back on the hammer.

I wasn't aware of the different color springs.
I had a Colt Match Target Completion, 20" barrel with the two stage JP trigger.
It had the yellow spring.
I purchased my 15/22 about two months ago. It has the Blue trigger.
Too cold & too much Snow in the Colorado Mountains to go shooting.
I don't care for the indoor ranges. Their Ok, but I'd rather not.

$10 for 1# is a pretty good deal in my book (when you consider the cost of a new good trigger). I actually got about 2-2.5# off the RRA trigger in my PC model. On another RRA NM trigger I just put the yellow trigger spring in. That worked out well. Did not keep the JP springs in my Geissele S3G trigger although I tried them out. I felt 1.25# was a little too light.

Decided to take everything back out and do a little polishing. Rangefinder this Friday, so ill let you guys know how it goes. Judging so far by the snap caps, the pull seems a hell of a lot smoother.

This might be a stupid question, but what does a lighter trigger provide? From my understanding is it just to decrease the trigger reset for faster follow up shots? Also where can I find them? Seem to be out on Midway

Not a stupid question, at all; A very good one.

A lighter trigger pull generally yields better trigger control, less disturbance of the sight picture when pulling the trigger, smoother release. It may or may not affect trigger reset speed, depending upon the design of the trigger.

Trigger pull on Olympic competition firearms is measure in ounces, not pounds, all for the above reasons. I have two match pistols with pulls of 18 and 14 ounces; A dream to shoot.

JP springs yield minimal reduction unless one takes the time to polish the mating surfaces of the hammer and trigger hooks, BTW.

Yep.

Lighter/improved triggers make it easier to shoot more accurately.

A highly skilled shooter with trigger time on the firearm in question can run a stock trigger just as well. Rob Leatham could win the Bianchi with a Hi-Point.

Disassemble the FCG and use a very light touch with a hard Arkansas stone on the surfaces, being careful not to change any angles. If you know what you are doing, you can use white polishing compound on a slow speed Dremel felt wheel. Again, a light touch ...

Not really. Reset and lock time is usually a function of the trigger design not the pull weight. I found on both my PC and regular model that is is possible to shoot fast enough to not have the trigger reset properly. Springs don't really help that but in fact often make it worse because the lighter trigger pull allows you to move your finger faster. Happened on both the 15-22 stock trigger and the RRA trigger of the PC model. Only cure is a faster reset and quicker lock time trigger. One solution that many use is installing a Geissele Super 3-Gun trigger. With an S3G trigger in an AR you can dump a 30 round mag in 4 seconds flat. Not the only trigger that will do that as some like the AT AR-Gold or the Wilson Combat 3-gun.

AND THE VERDICT IS..... gun ran flawlessly! not one FTF! 225 rounds today at the range. I would say the yellow springs were a good choice

fwiw, the first time I went out with the JP springs a few weeks ago.. I had no issues. This weekend I shot CCI AR Tactical, Fed Bulk 36gn and 40gn, and Fed Automatch.. However I was getting light hammer strikes kinda randomly. The only difference was it was very cold this time around (I was seeing snow flakes). It wasn't the ammo since I saved all of them (5-6 rounds) and shot them out of my bolt gun just fine. I am going to try and use my factory hammer spring and try again this weekend.

If you are shooting in cold weather and not keeping the ammo warm enough to keep the bullet lube flowing you can have a lot of feeding, ejecting, and hammer strike issues.
In the earliest days of the 15-22 almost everyone I know swapped out to the JP springs and no one had any hammer strike issues. Later on many went so far as to put in a better AR trigger instead. I even had a combo that produced a 1.25# trigger, yet I had no light strikes so I can't believe that the springs are the issue with light strikes. The preponderence of evidence says that is not the solution.

yeah no problems ejecting etc.. just light hammer strikes. I could see a slight strike on the bullet. I also never had an issue ever with light strikes before i put in the hammer spring on the RRA NM trigger on the PC. My deductive reasoning is that something caused light strikes this last weekend at the range and springs were the only thing I swapped out. (plus the rounds fired fine in my bolt gun) I've shot in colder weather also without issue before swapping with a variety of cheap ammo. I'm just going to put back the hammer and leave the trigger springs and see what happens.
