B-ARFCOM member Probablecoltaddict picked up one of these finest bolt action sporting rifles made and and shared these great pictures .
a brief look at what I consider to be a well used yet well preserved example of a Steyr Mannlicher Schoenauer Model 1956 with factory installed scope mounts and a vintage Weaver K4-F telescopic sight.
First up are the right and left side general views of the rifle:
Next up are some markings starting with the manufacturer on the left side of the receiver:
From left to right on the barrel left side we have an inspection stamp, nitro proof stamp and year of manufacture (1957):
On the front left of the receiver we have an inspection stamp and the year of manufacture again:
On the bottom of the magazine we find the STEYR logo and the importer/US distributor, Stoeger:
At the top front of the receiver, there are more markings but the scope is in the way so it’s difficult to get a good shot of them. Fortunately, this rifle was ordered with factory installed, quick disconnect scope rings. So let’s get the scope off to get a look at those markings.
We start at the left rear of the receiver where we find this curious little mechanism (rear is to the right):
Notice the blued rectangle in the center of the frame with a “U” cut out of it. This is side of the mounting block for the rear scope ring. The block is held fast to the receiver with two slotted screws, one of which you can see to the left. There is a slot cut into this block from above to allow for a bare steel piece that also has a “U” cut in it. This piece slides back and forth and is held in place by two pins, the heads of which are visible on either side of the “U” cut. Additionally this sliding piece is pushed to the rear under spring tension and can be seen sticking out from the rear of the mounting block, forming a push button. To remove the scope, simply press forward on this button with the finger or thumb of one hand (thus lining up the “U” cut in the sliding piece with the corresponding one in the mounting block) while grasping the rear bell on the scope with the other hand and swinging it clockwise when viewed from above.
Once the bottom of the scope ring is free of the mounting block, release the push button and you have a situation as shown below:
Notice that there is a slotted screw on the ring where it fits into the mounting block. There is one on the other side too. These screws allow you to both make course windage adjustments and perfectly fit the ring to the mounting block so that there is zero side to side play.
Next, continue to swing the scope in a clockwise arc until it is positioned 90 degrees relative to the rifle:
Then you simply lift straight up on the scope to remove it from the rifle entirely. You may have to wiggle it a bit because it’s such a perfect fit.
Here is the mounting lug on the front ring:
And the front mounting point on the rifle:
notice the raised areas to the rear of the mounting lug hole and on the right side of the mounting point. These are slotted and engage with lugs on the scope ring to lock it down as you swing the scope into the mounted position.
An above view of the rear mounting point with scope removed clearly showing the retention and release mechanism:
At the rear and similar to the front mounting point, we have a raised area with a slot cut to lock the scope ring down. This system locks the scope on as tight as if it were screwed to the rifle and guarantees a perfect zero no matter how many times the scope is removed and replaced. I mean it is rock solid.
And now that we have the scope out of the way, we can get a look at the markings on the front receiver ring:
Notice how perfectly struck the lettering is. SCHWEET!! Also notice the fine stippling applied to reduce glare when using open sights. To a guy like me used to military grade firearms, this stuff is pure Art!! These were available in various calibers, some of which are a real pain to get these days. While I would have bought this thing no matter what caliber it was in, .308 was a nice bonus since I have a number of rifles in that caliber already. Back in 1957, .308 Winchester was a pretty new thing!
Next, we’ll take a brief look how you remove the magazine and the magazine itself once removed.
Here we see the bottom of the magazine when mounted into the rifle, front being to the left:
Notice the total loss of bluing forward of the STEYR logo. This leaves no doubt as to how the owner held this rifle. He must have had similar sized hands to mine because I noticed that when I aim using this same hold, my second finger just touches the right side of the receiver ring. I didn’t take a picture of it but sure enough, the bluing is rubbed off in that spot. I live for little details like that. It’s History literally imbued into the firearm itself!
Alright, back to planet Earth…..
At the front of the magazine base plate is a little circular hole through which you can see bare steel. This is the dismounting catch. Insert the tip of a cartridge into this hole and press down slightly while rotating the base plate in either direction. Below, we see the process just started with the base plate rotated enough that the catch has been disengaged:
It’s important to note that the dismounting catch does not secure the magazine to the rifle; that is accomplished by tongues at the front and rear of the base plate engaging slots cut into the bottom of the action. Rather, the dismounting catch only secures the base plate from rotating.
Now continue to rotate the base plate until the aforementioned tongues are clear of the slots in the action (rotating 90 degrees as shown is best):
Now, use the base plate as a handle and lift the magazine out of the stock revealing the inside of the receiver and the bottom of the bolt:
Lots of interesting things are going on up in there but that’s a subject for a different time.

And a right rear 3/4 view:
If you aren’t familiar with the Schoenauer magazine design, you’ll be baffled at this. That’s because it’s not a box magazine but rather a rotary 5 round design. as you load them from above, they spool around the central axle. There is no follower in the traditional sense and none of the rounds touch each other when the magazine is loaded. It’s a complicated but elegant design that is reliable and efficient. It is also part of the reason the action on these rifles is renowned for how smooth it is in operation. Normally, there is no reason to remove the magazine from the rifle unless you want to clean it. Unloading of a fully or partially loaded magazine is achieved by opening the bolt and pressing a button which then allows the cartridges to spill out from the top. Never unload a magazine by removing it from the bottom. It won’t be pretty and you may end up damaging something.
If you wish, the rotor can be removed from the magazine by pushing the rear of it forward and then lifting:
Because these rifles could be ordered in multiple calibers, magazines are specific to the cartridge being used. The rotor is caliber marked:
The magazine body is also caliber marked on the inside:
Here is a top view of the action with the bolt to the rear:
The lozenge shaped checkered button is used to empty the magazine. Simply push it and whatever is in there comes flying out the top. For such a refined design, it sure dumps out the rounds in a most undignified way but it is fast so it has that going for it. A keen eye will also see the rotor. There are a few other things going on but this is just a brief overview so we’ll leave it at that. However, I do want to point out how beautifully finished everything is. Most of what you are looking at is in the white yet there isn’t even a hint of discoloration after 63 years. That’s a combination of extremely good steel and extremely good maintenance!
