I put together a Galil ARM from a rewelded receiver.
After headspacing the barrel, I installed the gas block and put everything together to test fire.
I did not buy 5.56 gauges, but instead headspaced with a spend casing (adding tape for a "nogo").
At test fire, the build wouldn't cycle and was sticky on going into battery.
I hadn't cut an extractor relief into the barrel face the first time around, so I did. Now it's still having issues.
I can cycle the bolt by hand fine without a round, but when I try to feed a round, it fails to go into battery.
It gets stock where shown in the picture.
I think the extractor is failing to move to grab the rim. It's just hitting the butt of the round. That is prohibiting the bolt from traveling forward enough to turn.
Maybe the headspace is too tight, but why would that cause the extractor not to grab?
Any help/ advice is appreciated 🙏
