Contact ISMI. They make chrome silicon springs that lighten the trigger pull by a few pounds, depending on the fit of you lower parts. I havnt installed my set yet. They are supposed to be 100% reliable with no light hits

I believe its like gambling when one alters an AR-15's hammer/trigger spring tension... My experiences with lighter springs has convinced me to always use a low mass high speed hammer to help prevent light primer strikes... I have tried the 15 minute trigger job and also tried yellow springs and have found that with several types of ammo, due to lowering spring tension, will occasionally fail to fire... |

This is one of those "hold my beer" moments.

 Ok, hold the beer, but spill the beans ETA: I've done the 15 min job on my lower w/ DPMS LPK, got the pull down to a consistent 4.75 lbs. I've run M193 , Radway Green, and BH blue box without problems, (at least no light strikes), but figured if the lighter hammer improved reliability and shortened up the lock time, why not? Any downside? |

My personal opinion, the only downside would be NOT to use a low mass hammer... If you have an old spare hammer laying around, you can Dremel it to create your own, it would be just the same as a high dollar low mass trigger... |

Thanks for the advice shootersden. Hammer and dremel standing by.
Looks like trying it is the answer to the question, although I may wait 'til I find some rounds that don't pop- something about not fixing it if it ain't broke, ya know..... Any input from beer holders welcome, if you can set it down for a minute.  ETA: Anybody know how much a low mass hammer weighs? |

I install JP triggers and springs in all of my ARs with the exception of duty rifles. I still use the JP trigger and trigger spring but with a mil spec hammer spring. The only FTFs I've had were with .22 lr uppers and then a lightened hammer (dremeled off the hammer spur) solved the problem. The instructions that come with a JP trigger advise you to cut off the hammer spur when using lighter springs to increase hammer strike force.
