I looked around for the class 3 forum but couldn't find it. I sent off my paper work to form 1 my Noveske chainsaw lower. I listed a 10.5 inch barrel. Since things I have read around the internets tell me I have about 6 months to decide what configuration (rails, sights, etc) I want to go with. Time to forget I ever sent it off so come January it will be a nice surprise.
