GUARDER Stainless Outer Barrel for Marui M&P9 GBB Airsoft ( .40 S&W )

Overall great barrel. I assembled it with a guarder steel slide, front chassis and take down lever and except the first time i put everything together (assembling and disassembling the upper and lower was very stiff) now everything works great. The only downside is that the coating in front of the part marked with the "40 S&W" is already scratching off (after a week).
