JP yellow springs for stock trigger

[BiggieXD]

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?

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?

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.

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 used the yellow and red... red hammer yellow trigger... and some polishing and a little molly grease... works great...

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.

 

[WilsonFlyer]

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.

 

[BiggieXD]

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.

 

[reshp1]

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.

 

[erick1987]

just put the yellow springs on mine tonight. used a dremmel with a pollishing disc and some compound. 15 min job. a lot smoother and a small but noticeable difference on trigger pull.

 

[BiggieXD]

Erick... When are you going to put some round down range to test your springs?

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.
