These devices are designed to hold ten cartridges of .450 Bushmaster ammunition, a large-bore, straight-walled rifle cartridge developed for hunting and some tactical applications. They provide a means of storing and feeding rounds into a compatible firearm. Typically constructed from metal or polymer, these components are vital for the firearm’s operation. Different manufacturers might incorporate distinct features like anti-tilt followers or transparent windows for round count visibility.
The limited capacity offers a balance between firepower and controllability, potentially beneficial in specific hunting scenarios or for those who prefer lighter, less cumbersome magazines. This particular cartridge gained popularity due to its effectiveness on large game at moderate ranges, influencing the development of associated firearm accessories. The advent of modern materials and manufacturing processes has led to more durable and reliable magazines for this specific caliber.
