The nail in the coffin was the 40MM rifled barrel. And I don't think that the taliban craftmen are capable of CONSISTANTLY turning out a rifled 40MM thin wall barrel in 7075 Aluminum.
Smoothbore BBL's are easy. But there is not real point if you cannot hit what you aim at. We could do it like that, but who would want to pay 3-4 K for an inaccurate launcher?
If someone wanted to put 50% down, and we had 15 people, yah no prob we can do it....but again, prove there is interest by putting the money in our hands, then wait 6-8 months for the 40MM smoothbore.
