Noted, I'm new to rifle building.. I have another AR in 7.62 x 39 and have had AR in 9 mm, never had problems before.This one first actually in standard caliber .
Appreciated everybody for helping out, I believe this tread can be closed.
Wish I had explained it more clearly the first time.
You should find the hammer once fully tensioned with a properly installed spring will give very reliable ignition of primers. Report back if this clears up your issue. Good luck and good shooting!
I assume you have turned your hammer spring around?
