MDT Metal Magazine 3.715″ .300 Win Mag 5-Round
The MDT Metal Magazine 3.715 300 Win Mag is a five-round metal magazine designed for compatible long-action rifles using the 3.715-inch AICS magazine format. In addition, it provides a detachable magazine option for compatible MDT stocks and chassis. However, magazine length alone does not guarantee reliable feeding. Therefore, confirm the magazine inlet, catch engagement and cartridge compatibility before use.
MDT Metal Magazine 3.715 300 Win Mag Features
-
Five-round capacity: As a result, this magazine provides a five-round option for compatible long-action rifle configurations.
-
Metal construction: Furthermore, the metal body provides a detachable magazine option for compatible rifles. However, the rifle’s stock or chassis must accept the magazine.
-
3.715-inch format: Therefore, check the specified magazine length against the rifle’s inlet before selecting a replacement.
-
Adjustable feed lips: In addition, feed-lip position may require adjustment to suit the intended cartridge and rifle configuration.
-
Multiple cartridge applications: Because cartridge profiles and overall lengths vary, test each intended cartridge and rifle combination. Otherwise, you may incorrectly assume that one setting suits every application.
For compatible Howa Long Action builds, the 3.715-inch format may be relevant when checking magazine fitment. Nevertheless, confirm the stock or chassis inlet and magazine catch engagement before use. Additionally, check how the cartridge presents from the magazine. Consequently, do not assume that every long-action cartridge will feed reliably from the same magazine setting.

Because cartridge dimensions and bullet profiles vary, treat these measurements as starting guidelines rather than fixed settings. In addition, test feeding with the actual rifle and intended ammunition. If feeding problems persist, reassess compatibility before making further adjustments. Therefore, consult a qualified gunsmith when the correct adjustment is uncertain.
