I bought the same gun but the black version and they are great guns at least in my opinion. You will have to downgrade the spring though. I bought mine for Vanguard also but it chronoed at 350-355 fps, give or take a few. I did break my blowback by not being careful when I took the gun apart, but it didn't hurt the performance of the gun. If you bought the one with the metal ris, it is very sturdy, no wobble. It's a great gun and serves me well.
