MambaMag Bottom Metal Description

MambaMag bottom metals were designed to convert a factory stock with floor plate design to work with a MambaMag detachable box magazine.

Details:

MambaMag bottom metals are machined out of 6061-T6 aluminum, with a steel mag latch. The bottom metal is designed to have a mag latch at the rear, but also have a front catch to give the most stability for the mag and the most reliable feeding.

Mounting and compatible accessories:

The MambaMag bottom metals come with all the hardware required to mount them onto your stock. They are also designed to require no modifications to the stock and allow you to very easily replace your factory bottom metal with a MambaMag bottom metal. The MambaMag bottom metals are compatible with MambaMags corresponding to their rifle type.
