Put together my first 3d2a item, and I'm having an issues where 9/10 rounds don't fire.

I get the occasional fire and cycle, but it's seemingly random and very rare. I checked everything over and cleaned it up(CLP) and it's still not firing.

I have a remixed lower that accepts CMMG conversion mags, a CMMG conversion bolts with the adapter collar removed and a RTB 22lr collar fitted with a RTB 22lr barrel.

Can you guys take a look at the pictures and let me know if you see anything obviously wrong?

edit: Yup, hammer spring was upside down. Flipped it and went outside and it fired 5 rounds and cycled just fine! Yay!
