INSTALLATION INSTRUCTIONS
Mill magazine box mortise rearward as shown in (figure 1), just long
enough for the extended box to fit. Shorten face of bolt stop .110”
(figure 2) to accommodate extra box length. On Win. M-70 actions,
the ejector and bolt stop will need to be modified as well.
If using the staggered feed extended box on the Rem. M-700 in the Ultra
Mag. calibers, it may be necessary to remove the top 1/8" of 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.
When fitting the center feed magazine lips, bend the lips in until it takes medium
pressure to push the cartridge through them. When doing this, make
sure that the magazine lips DO NOT contact the action rails. If allowed
to do so, this will cause a bind during the loading process. To correct
this, simply shorten the magazine lips and bend them in farther. This
design is not of the in-line type. The cartridges will sit in the box
staggered and will pop to center when pushed forward.
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 mortise. Some models have had this done allready.
The CFE-9 box requires more alterations than the other Remington style
boxes. The magazine mortise will need to be moved aprox. .250" to the rear, ejector
shortened to accomodate the extra length, and the ejection port moved back .250".
