AR disconnector

[EvilKidsMeal]

okay pardon the noob thread here. i recently built my first AR-15 lower (PSA stripped with PSA LPK and Magpul FDE furniture)(upper is on its way!)

my question is about the disconnector on the trigger, and hopefully my description will be good enough.

okay bear with me...the pin goes through the trigger and the disconnector at the same time, the trigger has a slit where the disconnector sits on a little green spring. the disconnector kind of see-saws on the pin inside the slit on the trigger. so you can push the disconnector down into the slit with a finger and the little spring pushes it back up.

now my question is, is it normal for the contact between the disconnector and slit on the trigger to be rough? i can push the disconnector down with a finger but it is somewhat resistant, and it feels distinctly like metal on metal. the spring resets it fully as far as i can tell, but the roughness worries me. hammer lock and trigger reset function flawlessy, but since this is my first build i want to make sure i do it right and everything is good to go the first time.

hopefully this all made sense.

Its too early in the morning for me. But when I built my lower I went to youtube and looked up a couple of the builds on there and walked through a couple of them. This might help ease your mind on doing things correctly. I would give you a couple links but I am getting ready to be running late because of this forum again.

As long as all the holes line up and the pin goes through, you should be good to go.

I have a Daniel defense I am trying to build and I can't get the pin through the trigger and disconnector when it's not in the lower should I drill it a little or call Daniel defense?

Did you put the spring in upside down? The disconnector spring has a flare on one end and that end should go into the slot so it holds the spring in place. If you put it in upside down the flare will scrape every time it compresses.

It won't affect function for the most part but it can wear parts prematurely and *might* cause issues later.

you know what i think i did that. i'll flip it and see if the helps. thanks i didn't even think of that.

It helped that I just built another lower last night so it was fresh in my memory and I had gotten to wondering what difference the flare direction made (I'd always just assembled from directions, last night was my second just from memory) so I swapped it to see and got the same issue you described.

i used the printed instructions from AR15.com, and i used a youtube tutorial, all went together easily and cleanly, i just didn't realize the disconnector spring had a specific way of installment.

Ah, right on.

Those are good, too.

I thought the coil size difference made the orientation rather obvious.
