MBE-08 Magazine Box


This box is designed for the Win. M-70 Long Action.

It incorporates windows for the larger diameter cases, or may also be used for the std. cases.

This box allows for an O.A.L. of approx. 3.825″.

The receiver, bolt stop, and ejector, must be altered to use this box.

Outside length is 3.910″. Inside length is 3.825″.


  • Mill magazine box mortice rearward as shown in (figure 1), just long enough for the extended box to fit.
  • Shorten face of bolt stop .110″ (figure 2) to accomodate extra box length.
  • If using the staggard feed extended box on the Rem. M-700 in the Ultra Mag calibers, it may be necessary to remove the magazine lips on the box to expose more receiver rail. Failure to do this may increase the chance of ratcheting of the cartridges from the box when operating the bolt quickly.
  • The extended boxes may or may not fit the factory bottom metal. The easiest cure is to relieve the back of the magazine box so it sits on top of the bottom metal instead of in the mortice. Most of our boxes are allready cut for this.
