ANS X5 (mech cocker)
Dye boomstick / Powerlyte Scepter
Barrel kit = changeable bore sizes.
Hard to take off autococker.
Got a Scepter kit for my ANS X5 mechanical cocker. The kit works great; always having a good paint/barrel match is key with a closed bolt gun even moreso than an open bolt since the balls will roll out if the barrel is too big.
Accuracy is great, except after breaks. I don't know why I was breaking paint yesterday, but I was. I don't think it was the barrel, most likely it was the paint - it may have been old, I don't know.
Removing this barrel is sometimes impossible. The back of the barrel is shorter than my front block components, so I can't grab around it. I can only grab the sides with my fingers. If it is slippery or my hand is from paint spray, I can't get it off. This is only a problem during games, since between games I can use something to clean it and my hands to get a grip again. If you don't have an autococker, this will not be an issue.
I have the 7-bore kit, and I'm glad I did when I played two days ago - I had to use the .680 insert for the paint I bought.
If you want a barrel kit (and who wouldn't?), this is a great way to go. It costs a bit less than a Freak and works great.
