SVT-40 scope mount installation

I've never been afraid of admitting that I occasionally have the dumb guy/What am I missing? moment and today is one of them.

I recently ordered an SVT-40 scope mount and VOMZ scope from Corwin (can't praise this company enough) and for the life of me I can't install it. The base slides down the rails without much issue and then it simply reaches a point where it's not going to go any further.

I removed the cross pin but that doesn't seem to solve the issue. When I reach the limit of where I can slide it, I feel a slight give from the internal button behind the cross pin, but not enough that the scope mount is going to go on even with some force -- or at least more force than I am willing to employ at the moment.

So what am I missing? Is this a case of Soviet hammer to get it on time, or am I just having a truly dumb guy moment?
 
My two snipers have almost same issue with exact mount, i had to really push hard to manage to slide the crosspin thru mount. Nice tight fit after that mind you. I think those mounts are spec'ed out for the real notched receiver so maybe a field notch just isnt wide enough??

You at least got to that point. I still have not quite .5 cm to make up from where the mount should be (I think) before I put the cross pin back in. Like I said, I've reached a point to where the mount isn't going to go on unless I go Ivan on it :)

I'm amazed that there is nothing on the internet about installation.
 
What kind of notch is it? The "field" notches and real notches are quite different and might account for the .5cm you are missing? I think these mounts were based on original blueprints. Maybe someone with more experience will chim in but thats my best guess. Also is the button at rear of mount adjustable?
 
From what I can tell there is a button on the inside of the mount behind the cross pin that seems to have some sort of spring in it. When I slide the mount on the rails, that button makes contact with the top of the rear of the receiver. When I push on it I can feel that spring but it moves only a few millimetres.

Like I said, I must be missing something. This can't be that hard.
 
I have read that the rear of some receivers (rails no notch) are squared off, others slightly rounded. The rounded one may not have enough material for a proper field notch to fit the mount.

Best way to do push it to final position is either release tension screw on top so the plunger moves easily or place the rifle on your boot and squeeze the mount into final position then insert the pin
 
I've had 3 of these repro mounts and one had a buffer spring that was way too strong. I cut one coil off it and it was then possible to push the mount home with reasonable pressure. But as bought it was nearly impossible to install on my real snipers which all have the very precisely machined Tula notch.

How did you manage to brake that pin? It is hard to snap it. Just PM me your shipping address and I will mail you another pin today
 
I'm not sure how it happened. Dumb guy moment without a doubt. I'll PM you and insist on paying for the pin.

There are some good Yanks too, ha ha. Hey, I had to fess up -- not like the pin was made out of chocolate. If I broke it, it was likely due to my own stupidity. It certainly was on full display trying to get that mount on :)


Just to update Martin refused any compensation for a new pin, and I know better to argue with him, and sent one in the post. I praise Corwin Arms for a reason, they are one of the finest Canadian firearms/accessories dealers out there.
