What part of Texas are you in?
+1 on insufficient gas based on the information you have given. You didn't mention double feeding so that makes an extractor or ejector problem less likely. Sounds like the bolt carrier is short stroking.
Troubleshoot your gas system starting with the gas block making sure it's aligned properly, tight and sealed. Inspect the gas tube for proper fit into the gas block, look for ruptures and make sure it is aligned properly with the carrier key. Check the carrier key and make sure it's tight. I've had one myself that one of the screw heads was torqued off at the factory and staked in. Nothing looked out of place but I was having the same problems you are describing.
Start with this and let us know how it goes.
