I may stir up a hornets nest here but: Current Scorp is a No-Go from a military field-maintenance point of view.
I don't think the Army would ever go with the Scorpion because of the current design of the FCG. There are too many small parts that don't intuitively go together! I was a combat arms officer back in the day (arms room officer as well) and I have done the HBI spring deal but what a mess and how would GI's, who are all thumbs, deal with that mess: while tired, in the dark, in the rain...
I like the Scorp, but to me a guy w/ former Army experience, who now primarily shoots, and totally trusts, civilian copies of military guns (AK,AR, FAL, M1911, M92, Sig P226) I just do not get the same confidence level from the Scorp. (I can't explain why, but it just does not have a "military" feel about it - more like a Ruger 10-22) If CZ reworked the inner workings of the trigger - to make it soldier proof - it might have a chance. I would rather them update the MP 40. I am old enough to have used a Grease gun in 1984 in Germany. They were simply bullet sprayers but simple to work and maintain. (Am not recommending these!)
I know that you may have fired thousands of rounds through your Scorp, or that some military forces have adopted them, however my main point is that in a prolonged "field" environment I would not want to be responsible for repairing, maintaining, and training soldiers on this platform.
This forum is replete with countless CZ Scorp "issues" and we are not even talking about magazine reliability/durability which is HUGE in military arms.
