SGM Tactical is a company founded on the belief that using modern manufacturing processes, better products could be designed. The Computer Aided Drafting systems used to create a higher quality magazine led to an ability to produce many items to a higher standard. All SGM Tactical products are manufactured in an ISO 9001:2000 approved manufacturing facility here in the U.S.A. SGM Tactical Saiga magazines are molded from composite/glass-filled polymer, ensuring reliable feeding and extreme durability. The springs used in these magazines are slightly longer than most magazines on the market, providing uniform pressure throughout the entire magazine.Notes: Will fit up to 3" shells
