Excellent Communication and Service January 15, 2017
Reviewer: Customer from Auburn, WA  
Fortress Tactical answered my questions very quickly and in a very friendly, personable manner. The ordering process was easy and my shipment came pretty fast even though I chose the least expensive option. I would recommend Fortress Tactical to my friends.
