Problem with new AR build

[O4L]

I don't know, I'm gonna have him bring it back over in a little bit, the more I keep thinking about it, the more I think we HAVE to have put the hammer spring in backwards. I gotta pull it apart and check that first. There's just not many other possibilities.

I'll update when I know more.

That's my guess.

We have had several threads in the past with the same issue of the trigger spring installed backwards. It’s not uncommon and easy to do.

I'm not even close at being an armorer, but I did spend Sunday night at a Holiday Inn Express (Warner Robins, GA).
I concur with checking the hammer spring:


But during Army Basic Training (41 years ago); It was repeated quite often, and quite forcefully about not mixing the bolt carrier group on your rifle (weapon) with another rifle (weapon) -- Headspace, but to be honest we were training with M16A1, that were not that new!!!!
It shouldn't be an issue using new quality components, but, maybe the parts were made Tuesday morning , after a 3 day holiday weekend.

Hope everything works out OK !!!!!!
