Design & Durability

MDT engineered these magazines with serious durability in mind. The high-strength polymer compound resists impact and environmental stress. The magazines have survived vehicle testing—literally driven over by cars and trucks—demonstrating real-world toughness. The tempered steel spring ensures consistent feeding across supported calibers.

While no magazine is truly unbreakable, this design represents a significant step forward in polymer magazine reliability for precision rifle applications.
