They are non production guns. Meaning no co like koah or rife makes one. I have two friends that build guns, both named Jason. This one was built by Jason Bihari m.ru-vid.com/show-UC2F72XR2p_9LL-50w4Iolywvideos In both cases they don’t build many guns just because it is tedious and time consuming. JB does have one from time to time to sell but it would be a bidding war for sure.
