[ARCHIVED THREAD] - Trigger problems question

Posted: 6/11/2014 8:04:40 PM EDT

Recently completed my first budget build. I used a complete upper (Hardened Arms) and assembled the lower. When firing, the trigger occasionally seems to not reset...sometimes I had to slightly push forward on trigger to reset it for next shot.
I used an inexpensive PSA PTAC lower build kit.
I only have 20 rounds thru this. Do you thing this just needs shot and broke in? Or is there something I should adjust on the trigger assembly?

Make sure the disconnect spring is not in upside down.

Check that the trigger spring is not installed upside down.

check the disconnector spring has the big end down and put some tw25b on all contact points and pins

My guess would be the disconnector spring.

I was shooting a lower I built with a ptac LPK. same thing happened to me, the trigger was not resetting, I put a little lube in there, and after about 20 shots it quit sticking. I shot about 300 more rounds that day with no other issues.

The trigger spring was installed incorrectly...rookie mistake.
Fires great now and trigger functions as it should.
Thanks for the help!

Glad it was an easy fix and a learning experience.

Easy mistake to make.

How do you think I knew to post that...
