My first thoughts are that there is not enough gas. Check that the gas port on the barrel is correctly aligned with the gas block. Measure the barrel gas port size (you can use a number drill bit shank in a pinch). If it has an adjustable gas block double check that it is open enough. Absolutely follow the manufacturers directions for warranty work, but if you did the assembly check that it was done correctly. Best of luck!
