havent tried the VSR-10 yet, but ya the accuracy is pretty good for what it is, and I heard that the VRS-10 clone (Well) had a cheap feeling and not really good (because of the excedent of grease in the gun). but this gun is not upgradable, (except if you want to put a spring in it that will boost the gun up to 550 fps, but it could break the trigger mecanism...) and a lot of people tell that it has the best out of the box performances...
