Gumby, your insights have been and always will be appreciated. This project was finished last year and I have shot over 400 First Strike Round through it (50 rounds in the field and the rest in a controlled environment during testing) without any guideplate failures. Of course that does not mean anything moving forward. I did account for it by ordering extra guideplates. I have an extra chain lying around that I can put into one of the first strike magazine. It was just painful to have to dremel out the metal risers in the chain. I know someone must have taken the time to solder each of one of them by hand. I will make the magazine modification to include the chains.
