Questions about square bridge configurations/functions?
#117050 - 16/10/08 10:34 AM

I'm curious about square bridges on Mausers. I've never seen one in person and you can tell I don't know anything about them.

In looking at archive photos, it appears to me that receivers with a single square bridge do not have a charger hump, is that correct? Do single square bridges have a standard height - might they be the same height as the ring? Are the square bridges there just for looks, or are they there for some function (I know that claw mounts were mounted on some, but in many photos I've seen, the top surface is just checkered or grooved)? Was there any rhyme or reason why some Mausers have double square bridges, some have a single square bridge on the bridge, and some have a square 'bridge' on the ring? Did all Magnum Mausers have them, or just some Magnums? Do some standard size Mausers have them as well?

Any enlightenment would be much appreciated.

Square bridges were built into some Mausers in order to simplify mounting scopes ( for double square bridges ) and to install receiver sights on single bridge actions. Since these were primarily European rifles, and claw mounts were in favor, the square bridges no doubt were a help.
The down side to them is that they added a little weight ( actually not much of a detraction on the heavy calibers) and made iron sighted rifles more blocky and a little less comfortable to carry.
Now days they are a bit of an anachronism ( there are some neat scope mounts currently made to fit them - like Joe Smithsons') but they still hold a certain classic appeal on large bore African styled rifles.

Re: Square bridges functionality, both of Speed's books show quite a few square bridge rifles where the square bridges are not used for scope mounting at all, or where only one of the bridges is used. Like all things, a fellow uses what he's got or what is available, even if the exact configuration is of no use to him and this applied even to the Ol' Timer Germans. Today, I suspect, most owners of square bridge Mausers who are building a rifle would feel compelled to use both "squares" in scoping it and if they didn't they might feel like the rifle wasn't "original" enough.

IMO unless used for sight or scope mounting, they really have no function.
It is interesting that many magnum length actions do have a rear square bridge and seemingly were not chambered in cartidges which are customarily scoped - as in dangerous game cartridges.
My open sight 416 has a square bridge, but my scoped 280 Halger did not and they are both original magnum length Mauser actions.
So, in answer to one of your questions, yes, they did make non-square bridge magnums.
Today, the square bridge is desireable due to rarity, and I assume all square bridge actions are looked at as pure sporter models - not military based rifles. Functionally though, no difference.
