ok i got a ww2 scope /and complete mount, the L shaped version ( pe_ ? )
i got a m91/30 rifle a good shooter / in good shape .
my terrible question
can the average gunsmith install this or should i seek someone who may, say speciallize in that mount to install
is it a tough job? any real tricky points to worry on?
its for my own pleasure, not to cheet or mislead,
have proper bolt handle on the way,
i am an open target, an i got big shoulders , but just want info on doing it proper .
thanks
 
Mounting it is easy, getting it to sight properly is not. The mount pad is ground to the reciever & the scope sits in the rings slightly canted. This is why most conversions don't shot all the well & original matched sniper cost so much. It can be done but I don't know off anyone who has the know-how in Canada.

What??....whadaya mean?

the mount is 'matched' to the rifle??.

I understand the mounts are set up so the scope 'leans' over the reciever slightly...this is so the scope is inline with the bore. If the mount was mounted 'square' the scope would be offset from the bore to the left slightly

Ya....Im doing the same thing as soon as I can make a rifle shoot well (stupid russian junk)
 
any points problems you discovered yet? like to hear any you found , besides the need to find a good shooter. to alter
thanks

I have never seen a mount that was ground to fit the receiver. Several years ago we interchanged the mounts and scope brackets between 3 original Mosin Snipers and verified zero with a bore sighter--- there was no appreciable difference (we were bored and this was something to do). I also have two orignal bases here, that were on rifles at some point and they show no evidence of grinding as they both have the same profile, as do the three reproductions I have had my hands on.
What you are probably thinking of is the grinding you MAY have to do to the scope bracket tabs to get your rough windage zero. This is pretty easy if you have a bore sighter as is the rough elevation adjustment before you stake the adjusting screws.

You can have the scope bracket canted too far over the receiver if you are not careful during your setup but the easiest way to overcome this is with a bore sighter a small machinist square and a good eye. The hard part about building a Mosin Sniper clone for most people, is finding the right size tap for the ORIGINAL screws (metric 6 x 0.75), some of the reproduction ones being sold on e-bay are sold with standard size screws.
 
ok since i am building this as a shooter, an not caring to misslead folks as to this being a copy, / a clone, would the type of attachmnt screws really matter as long as they worked / looked ok ? metric vs standard not a safety issue is it ? as to mount grinding seen comments on surplus gun site an on www. nagant site refering to that ...........??
thanks good info so far.

The type of screw used is not a safety issue, you just have to know if it's standard or metric, that is assuming you get the screws and pins when you buy the mount. If you do not have the screws/pins then just find a suitable replacement.

This is the part of the scope bracket that may need some grinding, most are manufactured with the tabs long so they can be final fitted.

Sorry thats what I was talking about. If I understand the mount correctly the scope was mounted slightly rotated by the person sighting it in. This was to compensate for the fact that the scope was to the left of the bore centerline. If it is not canted the windage would change as you moved out at different ranges. There is a drawing illustrating this at mosinnagant.net.
