Why the materials matter

Heat-treated blued steel body and follower

Heat treatment increases hardness and wear resistance, which matters where metal-on-metal contact occurs in insertion and ejection. The blued finish provides corrosion resistance and a low-glare surface, fitting visually with classic Enfield rifles while helping protect the magazine during storage.

Chromesilicon wire spring

Chromesilicon springs maintain tension longer than standard spring steels, resisting sag and reducing feed failures over time. For rifles that see intermittent use or that are carried in storage, a chromesilicon spring reduces the risk of spring-set and keeps rounds presenting consistently to the follower.
