MAC 10 Barrel w/ UZI Threads

Custom barrel for a 9mm MAC 10 threaded to accept a suppressor with UZI mounting threads. The external geometry of the barrel, as shown in the photo, duplicates that of the UZI with the barrel nut removed. Customer supplied the MAC upper and SAM installed the barrel. Per customer's request, the barrel is hot blued and contrasts nicely with the Parkerized MAC upper.
