PSA Premium full auto BCG with logo drops in to a milspec upper without any fitting. Ran 500 rounds through a class without a hiccup. Bolt is properly HPT/MPI tested. Solid budget BCG that punches above its price point.
PSA Premium full auto BCG runs reliably except the factory extractor spring was a bit weak. Had occasional failure to extract on the first 100 rounds. Swapped to a Sprinco extractor spring and its been reliable since. Quality otherwise.
