Anyone mount a PU scope on a SKS?

After much research, thought... dreaming. I have concluded that I will be mounting a replica PU scope and mount on one of my SKSes. Reasoning: I am not into tacticool SKSes, I want to keep it Russian-esque and of era. The mount can be bore centered and top reloading is permissible.

I have a Photopribor replica PU mount with Izhevsk markings. I will be getting one of their PU scopes after I find which one of my two SKSes is the most accurate.

The victim will be one of my two '53 Izzy refurbs. yes, I know. blasphemy. But I did try to sell them and I had no offers. It is too late now the bubba boat has sailed.

Has anyone else out there done the same? Mount a PU scope to an SKS? I know the base with need to be plained. But how much? Should I take off more than needed so that I can shim it?

Any help would be appreciated.
 
Seems to me that if you drilled and tapped the receiver of an SKS to take a CSA side rail, there'd be nothing stopping you from attaching a PU scope mount. Just make sure you get your height right!



 
Looks like this guy has the idea:

I drilled and tapped my previous SKS with a side rail to mount POSP style scopes on it (had a PK-A as well) definitely keeps the Russian appearance. I know with my side rail, it attached to the receiver, then dropped about 1" to actually give you a cheek weld. I've seen some pics of SKS's with side rail up at the receiver level and they seem way to high. Something to keep in mind anyway, not sure if it really helps.

Just to clarify a few things. PU mount as in 91/30 sniper mount and scope.

I know it can be done, and what methods people have used. I am simply asking for experiences in detail, of which most threads lack. Proper base width from receiver to keep the rings bore centered. Proper height so it's still possible to use the irons... etc.

I have considered the PSO style rail. But I do not like the offset scope. Also to properly use the PSO system on a SKS you must use an SVD style mount to keep the optics low. Fyn, you used an AK designed mount. If I were to use the rail system, I would attach the rail directly to the receiver (not the Molot or Tula style mount) and use an extra short Zenit-BelOMO mount.

And no, the PO4M-P is what I want and is easily available through eBay

All I can say in the 3 years I've been on GunNutz, I've never seen anyone mount a PU on an SKS. You might have to be first.

Can you mount a PU out of the way of the ejected casing, clear of the stripper clip guides, clear of the iron sights bore centered and still be happy with the eye relief? I don't know, that's a pretty tall order man.
 
Mounting a PU on a SKS would be simpler than a Mosin. Just get it straight to the receiver and shim it out or grind/file/mill it in to center the bore. From that picture it would be easy to calculate measurements. You can mod the SKS ejection port to make cases come out sideways so clearing any scope is no problem.
I have a PU Mosin Sniper and yes, eye relief is short. You'll need to get your face up close to that PU scope. Understandably with a bolt action sniper with one shot then slink away back into hiding, but not practical with a semi for rapid shot follow ups. A modern scope with better eye relief would be faster and more enjoyable. I'd get a PU mount with 1" scope rings like the picture shows. That mount looks a lot lower than an original PU mount.

Like SoBored, how about being the first? It would make an interesting thread.

The original PU optics are outdated, yes I agree with you on that. The eye relief is roughly 3 inches. So I will take your word on being uncomfortably close for a semi. I have zero experience with semi-autos , that is why I am asking around.

I will not be mounting an original PU scope. The only replica that seems to fit my fancy is the Photopribor. Which is a modernized PU scope. The ones from the Ukraine on eBay are these scopes with added replica markings. I have read hese have excellent optics and are of extremely high quality. The magnification is 4x instead of 3.5x and the eye relief is about half and inch shorter then an original. The diopter adjustments are achieved by the optic internals and not just the reticle. But this is still not a sure choice. The only good optic that is available to my needs. VOMZ... forget it!

Thanks for the input so far.
 
I don't think the short eye relief will be a big issue, the SKS isn't big on the recoil. Just watch it with new shooters.

I went to Photoprylad's website and took a look. It says eye relief is 68mm (about 2.75"), OAL is about 6.7" and tube diameter is 24.5mm so that's good. With the eye relief that short and an OAL of about 6.7" I don't think it will get in the way of your stripper clip guide or get hit with brass. In fact, I just checked and with my SKS shouldered, I measure about 9.5" from the stripper clip guide to the lens of my glasses.

So that leaves it up to you to get the mount flat and modified to the point that it centers on the bore. Which you should be able to do. Even if you mess up you can probably shim it or get a piece welded on.

Still not sure about you being able to use the iron sights.

I couldn't find any info on the repro mount, can you provide a link for that please?
 
It's not the short eye relief that's the problem, it's more getting your head up far enough to it that strains the neck muscles for me with the original stock . Coupled with a chin weld I found it a workout sometimes firing the Mosin sniper, so I added a Blackhawk cheekpiece and problem solved. Lack of pistol grip with military triggers is something else to overcome a bit too.

All in, it's fun to shoot, but modern stocked guns are much easier.

I was aware of the differences between the AK and SVD mount, I just happened to find two cheap optics that had the AK clamp. I was initially going to switch to the SVD clamp, until I actually shouldered it and realized I had an awesome cheek weld and had no problems using the irons or optics. I'm left eye/left hand though, so non-southpaws may have a different experience. If you can't find the technical info that your looking for, I'd to love to see a write-up in this thread. I wouldn't mind a new SKS project.
 
I have done the calculations as well. I know it will work. The front of the scope will be as far forward as posible. I notice others mount the scope too far back. Most will argue about the pull of an SKS stock and how it feels uncomfortable. This is not an issue with me as I am an adaptable shooter. My father always told me "if the gun doesn't fit you, you must fit the gun". Follow up shots is not a priority.

I have a cheek weld in mind. I am modeling my design after the SHS-14

This rifle is where I got the idea to mount a PU scope using the Mosin style mount.

I am considering a custom base for the scope mount. The PU base design will remain the same with the exception of a flat base, and a redesigned thumb screw placement and locking design so it will not protrude. I have been refreshing my AutoCAD skill recently. Yeah it will cost a bit... but if I can find a market.

It's in the works
