Our Team
First of all, every person involved in this project is a firearms enthusiast. Between us all, we have a combined experience with firearms of more than 150 years; and we’ve all served in various branches of the US Armed Forces. We like to think that we know what we’re doing. ASF Magazine has grown thanks to a group of gun enthusiasts that came together to form the Anti-Spring Fatigue (ASF) Rifle Magazine Company, fueled by their passion to create and sell 30-round magazines for the AR-style platform that would never succumb to the dreaded spring fatigue,
