rem clone internal box magazine question

Hi,

I'm in need of advice about how to best assemble the internal box magazine on a rem. 700 clone rifle I'm building . I'm a relative novice at gunsmithing and assembly so appreciate any help.

The rifle is a .308 win, with a Defiance Anti-X action, Hawken Oberndorf BDL bottom metal, and a rem 700 clone internal box mag. All are Remington short action.
The issue I'm concerned with is that there is a lot of "slop" inbetween the magazine metal and the action. The grooves on the bottom of the action which receive the upper edge of the magazine measure about 3.1" in length and the magazine metal itself measures 2.8". So the magazine metal can slide about .25" forward and backwards in the action.
Is this normal or do gunsmiths spot-weld or otherwise attach the magazine metal to the action so it can't slide?
is it better to slide the magazine metal as far forward in the action as possible or all the way back or in the middle?

Thanks!
 
Thanks for the reply. The action I purchased was for standard rem SA. But maybe they got the order wrong. Or maybe they make their actions to fit both standard SA and extended?

I tried to call Defiance today but they are closed on Fridays. Trying to get this rifle built for a friends moose hunt in AK in a few weeks so time pressure is real.

Wondering if they did give me the wrong action if I can adapt for standard 2.8” mag length.


Ugh
 
The anti-× comes with 2 mag box options the wyatt box cut or DBM when you order, check your receipt should say

You've got an extended mag cut (Wyatt's box). Just put the Wyatt's box in it and call it a day. The longer box is compatible with all of the BDL bottom metal. It has a raised step on it at the back to work with the BDL bottom metal. There's really no negative to putting the longer box in it. Most everyone wants it that way and every Remington I do gets the action cut to put the longer boxes in them.

Call Defiance and see what they say but I bet you'd be time ahead just getting the extended box and be on your way.

For a 308 it's....

Hey, thanks for the full details and yes, you are spot on!

I spoke with Defiance and the magazine cut-out on their REM 700 clone actions are cut at just over 3” versus 2.8” for actual rem 700. Therefore the internal box magazine that fits best is exactly as you say. Wyatt’s MBE-5, NOT Wyatt’s RSA ( rem short action)

I called Wyatt’s today and swapped the RSA I had ordered out for the longer MBE-5 and they were super helpful.

If the gun doesn’t cycle shells like a smooth butter churner once I get it all put together I’ll follow up on this thread. Otherwise case closed !
