The pistol adapter they sell is the same threads for a standard milspec AR buffer tube, you have to order the correct thread and type of screw to hold it centered and in place but the design is ingenious and perfect like all other KAK industries products. I wish they could pump out more ideas. And I need a barrel thread adapter *cough* for a reasonable price.
+ all of the KAK stuff is made here in the USA
