Just wondering who uses the J-P hammer and springs. Are they worth the cost?
I run them in a couple of different rifles. They work great! I would suggest getting his adjustable gas block though too that way you can control the port pressure.

For a match rifle, sure.
For a defense rifle, I recommend against it.
I have one, but removed it after it resulted in light strikes on several different ammo types. I would tell you what those were, but it’s been too long ago for me to remember, except to say it was not Russian made ammo.
A swap of the lightweight hammer spring for a the stock spring did not completely solve the problem.
A swap out of the JP hammer for the original Colt, but retaining the JP trigger provided a nice trigger feel with reliability.
Yet another reduced mass hammer experience. About 2 yrs ago one of my guys was using a similar lightweight hammer in his RRA (stock RRA parts). It, too resulted in light stikes. He now has the standard hammer and trigger in his RRA and it works 100%.
Good point and even JP says that in a real world rifle, don’t run his hammer or yellow springs.
His trigger is the heat though with stock springs and hammer.

Seems like most here are: “operators” or “tactical _______ (fill in blank)” or “stationed” - reading the way people post around here is like something out of a Tom Clancy book.
I, on the other hand, am just a civilian gun owner. I shoot as a hobby. Preferred sport is 3gun/multigun.
If your AR-15 is intended to be a home defense gun, OR you use it in your line of work (whatever that might be), then the extremely light trigger you get from the JP springs is not appropriate.
Another reason to avoid them: light strikes. Use both springs together and your rifle probably won’t set off military primers (mine wouldn’t).
I now use only the yellow trigger spring and I reload with Federal primers - or use Wolf for really close stages.
JP springs definitely make for a light, fast trigger pull.
If your AR-15 is intended to be a home defense gun, OR you use it in your line of work (whatever that might be), then the extremely light trigger you get from the JP springs is not appropriate.
Might depend on which ones you use. There are four (IIRC) ranging from 3 to 41/2 pounds. I run the four and have never had a problem.
Even if you use a particular firearm in matches only, you want it to work. Blowing a stage due to a preventable issue at a local match = not fun.
Even more so if you’re attending a major match (or a class) and you’re spending $$$$ on travel, hotel, match fee, food, etc.
Even more so if your match firearms are used (or might be used) for real world purposes.
Now I have had to rely on my M-4 rifle to save my life but now just for fun/3 gun for the most part.
I have 3 complete JP-15s (cheaper versions) and even shooting with the LMOS carrier, full JP trigger group and shooting either green tip or almost any other mil ammo I have had no problems at all. After almost 8000 rounds of almost exclusive Army ammo I have had no problems with the JP system.
If you are having problems please let John at JP know and try to let him work the problem…he is very busy but never to busy to talk and make things right with his products. Always give the manufacture a chance…they can’t fix something that they don’t know about.
Just my .02 cents
