PSA full auto nitride BCG cycles reliably for several hundred rounds. The nitride finish marks up easier than I expected from carbon scraping and brass contact. Function is unaffected, purely cosmetic. Good budget BCG.
PSA full auto BCG with the nitride coating runs cleaner than my old parkerized BCG, carbon scrapes off with a rag instead of a brush. Bolt is properly HPT/MPI tested. Gas key is staked from the factory. Solid budget BCG that punches above its price point.
