Everyone’s advice is spot on .Use process of elimination . Start with the mag and work your way down .
If all else fails I’d make sure the gas block is aligned properly.
To check for gas alignment , takeoff the scope remove the upper and the bolt. Takeoff the handguard.Then blow down the barrel from the muzzle end while plugging up the chamber with your finger . If you’re not getting a good flow through the gas tube,loosen the block and turn it .
That method has been working for me for a long time.Always works perfectly
