Default Cycling issues

So I took my first AR out today. Built it myself and I can't get the dang thing to cycle more than 1 round. I'll rack a round, bang, usually it ejects but it won't chamber the next round. I had a lot of stoppages. Mostly fail to feed and a few double feeds. I'm guessing I need to adjust the gas pressure but I can't figure up or down.

When you pull the charging handle all the way to the rear, and hold it there - does the bolt head disappear behind the ejection port? Or can you still see a portion of the locking lugs on the bolt showing in the port?

good pics of the rifle especially the upper reciever from the underside. pics of the buffer buffer spring and bolt carrier. really good closeups of the carrier itself and the gas block

This is bolt caught open on bolt catch. When I pull charging handle all the way back it disappears.

those look ok.

can you take the handguards off get a real good close up of the gas tube as it enters the upper and a good close up of the gas block??

the bcg looks staked would like a real good close up of the gas key on the carrier

with the bolt extended will it stand on the bolt without the bolt retracting into the carrier??

how many gas rings are on the bolt?? there should be three

causes of not cycling is always an issue with improperly assembled gas system parts or incorrect parts put together or a mis-drilled barrel

The bolt will stand without collapsing. The BCG looks good. I'm trying to take the hand guards off
