Due to the maze of ITAR and export regulations on firearm parts, only a specific few of ours are currently for sale outside of the United States to select countries. As most non-combat shotgun parts are exempt from ITAR and conform to the EAR99 caterory for export, we have begun selling specific combinations of our parts to customers in Canada, Germany and the United Kingdom. If you reside in one of these countries, please make your purchase from our International page only. International orders generated from elsewhere will be cancelled.
