Yes we will take orders but they will be definite orders only. We will require payment details and when they arrive we will simply charge your CC and ship. The B&T adapter is designed to work with the 7.62x39 CZ 858, the rifle will require some machining. I see no reason why they will not work with the CSA guns in both 7.62x39 and .223, it remains to be seen what work (if any) will be required to fit them to these guns.
