Hey guys I'm gonna be changing the mill in my jato. Its got the dynamite .19 in it which I do like but I've done a lot of mods and shes a tank. I've been looking at the os .21 max or the picco max .26, or .21. All input greatly appreciated I'm leaning torwards the picco max .26 but I want to make sure it will drop right in no mods. I know the os will just not sure on the picco .26 thanks guys
