Help! My new build no pew-pew!

[JT]

So I finally ran out of build mistakes to make (or perhaps not!) on my CFF contest award-winning PSA kit, assembled the carbine, ran and passed all the static function tests, and took it to the range to do my active function tests.

When I loaded one round for the first test, I got a DNF. I (carefully) opened up and inspected the rifle and the ejected live round. I saw nothing wrong on the rifle. The primer was dimpled, but the round was intact. I repeated the test with another round and produced the exact same result.

I suspect a light primer strike, but it must be pretty marginal, imo. (Pics below.) Ideas, advice, friendly insults? TIA!

Is the hammer spring installed correctly?

that was my very first thought as well.

@JT...see if you can get a pictureof the hammer spring as it's installed now.

Make sure you firing pin isn't broken.

We have a thread-closing winner!!! Hammer spring in backwards, because by the video I used to do the install, it looked right, but my spring was just different enough to cause me to focus on the wrong aspect. Turned it around and received a glorious PEW! Thanks, @ripv2 and @Tim !!!
