Blitzkrieg Castle Nut
The Blitzkrieg Castle Nut is a Mil-Spec castle nut for any AR-15 and LR-308 with a carbine buffer tube installed. Made from steel and coated black.
The castle nut included will NOT work with rifle-style buffer tubes. A rifle buffer tube does not require a castle nut to be installed.
