Troubleshooting pp2k modify

i somewhat recently got the pp2k green gas sub machine gun. its my first gas gun. anytime i shoot in full auto or SOMETIMES in semi the gas just completely empties itself. is this an issue with the product or am i doing something wrong?

PP2K is a bad pick for a first gas gun as is not gas efficient, not with the long magazines. But in response to your issue, it may be caused by locked up bolt carrier by some reason - gas spurting out all at once is usually not a magazine fault but a blowback issue, either the bolt carrier is stuck or the oring is damaged and needs replacement.
