Desert Tech Steel Case magazines are engineered with a simple but effective integrated design feature to maximize accuracy that is usually overlooked by other manufacturers. The magazine is specifically shaped to follow the contour of the cartridge, locking the cartridge in place inside the magazine by the neck of the casing instead of the tip of the projectile. This helps minimize scratching, marring and damage to the tip of the projectile while ensuring perfect alignment of the cartridge to the chamber when chambering a round from the magazine. The trueness of the projectile stays pure and never touches the sides or end of the magazine where damage could occur. Durable high strength steel outer casing with strong impact resistant polymer base plate, spring guides and follower. Easy to disassemble and clean as needed. Now with durable Black-Ice coating for smoother operation and greater resistance to wear.
