Awesome, glad we still have the interest!
Having them machined is very pricey and they would likely have to be 2 pieces ( the "nub" being a separate piece) but, having them cast would be more cost effective, and more accurate technically. We are going for casting in aluminum to keep the weight down for trooping. I am trying to keep the price under $75 but we shall see once all quotes/info is received. Hoping these can be reasonably priced.
