Am I crazy or is the trigger spring partly responsible for the "crunchiness" in a stock GI (BM) trigger? I have a RRA two stage match trigger worked over by White Oak for my match rifle, but for work we're supposed to stick to a "stock" single stage jobbie. I carefully smoothed up the sear and lubed the snot out of it but still get the infamous crunchy creep. I'm not a trigger mechanic and don't mess with them much, but it looks like the trigger spring riding over the trigger pin? (I think with out looking at it right now) is partly to blame for this? I tried the trimming the spring thing on an old set of springs but didn't like it so I just stuck the o.g. ones back in. I was also going to pick up a set of "reduced power" springs and see what they feel like. I know this has been asked and answered at least a hundred times - so thanks in advance. |
| Not an expert by a very loooooooong stretch, but I had a couple stock single stage triggers worked over by bill springfield ([email protected] , www.triggerwork.net), one tuned to 4 pounds w/ standard springs, one tuned to 3 pounds w/ reduced power springs and a hammer w/ the hook removed. Both are great, relatively cheap, (about $30 and $45 respectively using my triggers), and turn around time was very quick, back to my door in around a week. |

I was under the impression that it is generally frowned upon to use reduced power springs in a duty weapon. I recall reading accounts of inconsistent ignition reliability with some primers. I will see if I can find them specific threads to back up that claim. here is the only one I could locate quickly: www.ar15.com/forums/topic.html?b=3&f=118&t=365255 joe |

I've used reduced power springs on my ARs for years. It definitely eases and cleans up the trigger pull. I've shot thousands and thousands of rounds of all flavors and have never not had a round go off due to a light primer strike. Anecdotal evidence only... but I'll keep using them. I'd reccomend some good CS springs from Brownells: Reduced power springs |

Not sure what you mean by crunchiness, but I am imagining a sort of grindy or gritty feel to the trigger as it breaks? If that is the case, you might want to try polishing the hammer notch and trigger sear. If that doesnt help, +1 on the Bill Springfield trigger job. For a duty gun though, you may want to tell him to keep above 5 lbs, no reduced power springs. Once I learned more about the function of the trigger mechanism, I actually re-tweaked my trigger to achieve a slightly heavier pull, but still nice and crisp. |
