I'm not really stating anything just yet, just composing posted info. Seems to be confusion as is it adjustable, is it not; if worn where would the toplever rest, etc. But for sure I would not attach much weight to the verbiage in the adverts. I have not seen any empirical data on the Helice, Helicobloc, etc. but as far as I know there is no gun that does not shoot loose. And the French are no exception. Outside of that, I'm just not sure for now.

Kind Regards,

Raimey
