Hey everyone, I have a Well M70c Vsr-10 MB10. I just installed a SP170 spring, ball bearing spring guide, and a T6 aluminum piston. I am planning on getting a MadBull vsr-10 hopup bucking. But I want to know what type of barrel to get. A 6.01 or a 6.03? I already understand the pros and cons to each, I Just wanted to hear some preferences, tips etc... Any help is strongly appreciated!! Thanks!
