I picked up a PSA build on a trade. Based on the appearance of the internals, it didn't appear to be fired much. After the first range outing, I noticed the reset was more of a thud and kind of shakes the gun. My other AR with mil-spec trigger is more of a tactile click. Upon further inspection, does this look like a diy trigger job? Everything looks polished and I didn't think mil-spec triggers came from the factory like this. Would you be concerned?

I have some mil-spec triggers that click and some that thud pretty hard. Some are just like that and I think the thud goes away as the trigger breaks in. Just oil it and shoot it. Your picture doesn't really show anything at all because of the overall brightness.

Yeah, it's hard to see in the picture, but the top of the trigger and surfaces where the hammer and trigger contact are shiny, bare metal. iPhones aren't the best for these types of pictures.

Looks normal for a standard mil-spec type trigger. Looks pretty dry, lube all the contact points with some synthetic wheel bearing grease. Trigger may improve with some more use.

Thanks guys. I wasn't sure if this was a cause for concern. I'll leave it alone and just keep shooting it. Enjoy your weekend!

The notch in the hammer is done the same way. |

Put a few hundred rounds through it and then see what you think of the trigger. I'll bet it'll feel really smooth by then...

Some triggers rest with a click some with a thud. I have ones that do both.

The right side shows it in place correctly, but the left side looks like it is not in the correct position, as in not on top of the trigger pin? Take a look, or take another pic of the left side. ETA: trigger pin, not hammer pin. |

Upon close inspection, it looks like it is running UNDER the trigger pin. Where in the hell is the arm of the hammer spring??? |

No, nevermind....further inspection shows that what I thought to be the hammer spring is actually the arm of the trigger spring. Where in the hell is the arm of the hammer spring??? Fortunately it's easy to replace the hammer spring. |

If you can't find it, it's time to replace that hammer spring. Some people trim hammer spring tails to "lighten" trigger pull. I don't like that, but it will lower perceived pull, at the cost of an unbalanced hammer spring - which can lead to problems. Your "thud" reset could be because of this... Fortunately it's easy to replace the hammer spring. Quote HistoryQuoted:
