Update for anyone that is following or finds this thread later...Kriss USA will NOT do any warranty work for us, even if shipped to and from a US address. They said north sylva is the ONLY option. Probably not their fault, I assume there are regulations in place. Still, I am not sure why finding replacement parts is being such a huge issue.
Does anyone know a spot to buy parts? I just need the damn mainspring, I am sure it is simply much too strong. I want to have one I can remove very small sections at a time until either the gun won't cycle at all, or it cycles properly.... damn this is frustrating.
