Hi guys, A friend of mine is offering me his AS-01. I believe its still stock parts. What do these rifle need to work well? I understand there are some issues with the stock rifle and not just bits that need upgrading, such as body pins or something along those lines. I'm thinking of going down the HPA route as I have a tank, regulator and airline at home from another project. Hopefully that would bypass the cylinder volume issue. Any more help would be greatly appreciated. Cheers Dean
