1st, I know I will get the “google it” or “search for it” replies. I did both. There is a lot of info out there, but none of it answered my question.
I have a S&W M&P15. The trigger pull is about 6lbs. I would like to get it at or just under 4lbs. I don’t want to spend a lot of money. I can afford a new trigger set, but I want to try this first. Why spend the money if I can do this.? From what I gather my options are the 25 cent trigger job or a new lighter springs with a polish job. I am comfortable with doing it myself. I also plan on installing the ¼-28 set screw in the grip screw hole. Will the 25 cent trigger job get me to 4lbs? Or will I need new springs with a polish job? If I need new springs, which ones should I get with my stock parts? I see a lot of web hits for JP springs, but every site I look at says the springs are for jp trigger sets. Brownells and Midway have a bunch of spring sets, but those sites aren’t clear on pull weight reduction or compatibility. thanks |
| i tried the 25 cent job and it did lighten the pull, but i just could not get my mind around a mod like that being reliable. i replaced the modded springs with Colt springs. i then just broke down and bought a SSA trigger. i now have a great trigger and a good backup. IMO do not mod fire control parts. |

If you want to screw with your trigger go ahead, but no intelligent person here is going to encourage it. |

so polishing the 2 contact surfaces is modding? polishing is not removing material. I have polished many triggers without any issues. IT does not remove material.
Back on the springs. Is there a spring kit available that is not specific to a drop in or full kit? Or does it take a complete kit to do this? thanks |

More modded triggers, except these don't malfunction. The JP light springs will work with a standard FCG. Everyone will tell you not to mess with your trigger and I agree to a point. I say as long as I'm not filing or changing parts, I'm ok. The JP springs you mention are a factory produced part, so you have some cover. Try just the Yellow JP springs and the set screw before even considering a trigger job, it's too cheap not to try it. These guys will also tell you to go out and pay +$100 on a new trigger. Well for me, that just won't happen. That's about 1/6 of the price of my AR w/o optics. Bigbore, I love your business and all, but what can go wrong with the mods I recommend? It can't malfunction and go FA. I'd really like to know, because I know that I am not the be-all end-all expert. I'm nowhere close. You certainly know your stuff, so I'm honestly asking you this question. Also OP, look down about a page, you might find and interesting thread.
OP, what exactly is the problem with your trigger? Just heavy weight? Long trigger pull, grittyness? They all require different methods to fix. As always, try your new trigger dry-firing a lot before you even consider a live round. When you're confident enough, try it with one round. Repeat this about 30 times to be safe, then 2 rounds, then 3, etc. Also, you are on your own if you do any permanent modifications to your gun and it malfunctions. I hope this helps sort everything out for you!

| I wouldn't touch the smoothing the break issue, as that would be polishing. I know, you're ok with it, but I personally am not. The JP yellow springs will lighten the pull some, read the link I posted, if you haven't already, as he uses the JP springs also. What kind of AR is it? If it is an M4gery or a fighting AR, I wouldn't touch it at all, I like extreme reliability in those types. The JP yellow reduced pull springs, have a bit of a problem with some ammo's hard primers. Another piece of advice, is to buy another FCG to modify, keeping your stock one as a known reliable. |

ok, i am set for now. I will order a set of yellow jp springs and leave everything else alone. thanks You're welcome, let me know how your trigger comes out as, since I am considering these upgrades for my own AR!!  Great choice, I use the JP yellow springs on most of my ARs now including on my SSA. They really work great! |

Just one more idea. On one Spikes lower, I replaced my RRA LPK parts with the Spikes battle trigger set. It started off pretty slick, but as the parts wear in together a bit, I have a much improved trigger. Still maybe 5# with the current springs, but improved over my other AR triggers. While nothing like a Timney or Giesele, not bad for a battle trigger.
And not bad for the cost, now play with springs a little and you might get it down to 4# or so. I like a light trigger on my bolt guns, don't really want anything like those on my ARs. I was kinda impressed with this out of the box Just another something to consider...

I installed a set of yellow JP springs. Trigger pull is exactly 4.5lbs now. Very managable. I should see better follow up shots in my next 3 gun. Other than a little gun grease, i id not touch any of the other components. If i want a better trigger than this, i will order a complete trigger group.
I will shoot it tomorrow, should be fun. |

I run the JP yellows on a RRA LPK standard trigger. I thought they were a great improvement and worth the little cash I paid for them. Have you had any light strike problems? I thought about trying those. No problems yet. I shoot mostly wally world Federal, but no problems with Wolf and Brown bear yet. |

Bigbore, I invite you to come on down and shoot my rifle. Gunsmiths have been cleaning up triggers for many years, ARmalite has instructions for stoning to tune their match triggers, and not eveyone can afford a couple hundred bucks to drop in an aftermarket trigger. Nothing wrong with a little polishing and a lighter set of springs. No one is recomending grinding or changing the geometry of the FCG. I finished up an Appleseed shoot today with my rifle. The round count is pushing close to 2000. I intend to keep posting as it grows. If the mods fail all will know when and where. If you find yourself in Florida, look me up and try out a home grown trigger job. Quoted:

Well, i put 100 rounds thru it. The JP springs feel great. The 4.5lb pull is perfect. The break is a little less crisp than before, but still that it isn't bad. I after i got used to iy, my follow shots on double taps were much easier to keep on target. The springs were a big improvement. No light strikes or other issues. I think 4.5lbs is the lowest i would want to go for this AR.
I will do the set screw mod this weekend. |
