Can anyone with a repro scope mount tell me:

How easy are they to take on and off?

If loose enough to slide on and off without a rubber mallet, are they too loose to hold zero? And is the cross-pin a hammer-out item regardless?
 
No need to remove the scope for cleaning with the original mount / repo mounts. That's why I used the repo mount on my SVT40 instead of those aftermarket ones that you have to remove to work on the rifle.

And they look way better anyways... :)

I have one of the repro mounts on my SVT. I cut the notch into my receiver in order to get the mount to stay on, before that I had no zero retention, since I cut the notch it holds zero fine. I've also never had a problem with losing zero when taking the mount off and putting it back on. Taking the mount off is a breeze, I simply take out the cross-pin from the side of the mount and slide it off. Might sometimes have to push forward on the mount to relieve tension on the cross-pin, but not always. I've also found that the cross-pin can compress a little when fully in the mount, this can make it easier to remove the pin. I can often remove the cross-pin with just my fingers, but sometimes I'll need to give it a little whack with a punch to get it moving.
Hope this helps.

Thanks for that video Dilligaf! It usually takes me ten minutes of swearing to accomplish what that video demonstrates in one minute of
no problem. Drat! I've been going at it wrong.:wave:
 
i used a bit of devcon when i set my scope in the groves... lol... So it ain't coming out unless I use a big hammer. I wanted to make sure they would be zero movement.

When I filed my notch, I made it the same size as the cross pin as well.

I know the original design had some back and forth movement on the spring loaded mount. Never found out why they did this.
 
The reason I ask is that I'm always nervous about packing/carrying it with the optics attached. They stick out, they are the least solid part, and they are alignment sensitive. In a previous life I used to design ground-mobile coms gear, and that combination is the kind of thing that really drives your warranty budget.

If it comes off readily enough then at least I can take it off for shipping.

I was also wondering if anyone has tried welding an offset universal AK side mount onto the receiver? It's not quite period correct, but it does go on and off readily and hold zero. The parts are cheaper, although the welding will cost more. It is also a more complicated load path to deal with. Anyone out there have experience with this approach?

Either way I have to modify the receiver, as I don't have a notch in the top.
 
Got the mount on EE for 50$ and the scope from westrifle for 120$, keep an eye out on ebay for the scope. Found that westrifle has better deals on their eBay page for some reason.
 
Purely anecdotal but I've found the repro mounts slide on my real snipers very easily but have no detectable lateral freeplay. On a couple of not-real snipers the brackets had to be pounded on and off. More importantly, on a non-sniper I've made into a repro by filing a notch I also found the axis of the bracket (and scope) is not at all well collimated with the bore. In fact, the post is so far left of center after bore sighting it that the scope is barely usable. With my original real snipers the collimation is near perfect. We know the snipers (at least in '41) were assembled from selected parts on a separate assembly line and, to me, the main goal was probably getting barrels that were nearly parallel with the flats on the rear of the receiver where the mount sits. I've read that real, original mounts have been found with evidence of filing and I wonder if that was done when a "field expedient" sniper was created with an original mount? I'm actually going to sit down with the repro mount today and see if I can't collimate it to my repro sniper with a bit of careful file work. Anyone else out there run into this collimation issue with either non-snipers or real snipers?

I picked up a repro from corwin arms a few years ago at a gun show. Works great hardly had to adjust the scope, but I can't bring myself to file the notch in the receiver. It holds true if I push it forward after each shot.
 
These also work - Corwin-Arms still has them.

The mounting/retention system negates the need for cutting the notch in the top of the receiver.


I did a whole write up on them here:

Yes, I know, they don't look original (because they aren't), but they work well, and allow you to mount whatever scop you want. And they do return to zero after removing and replacing them.
