Mosin Nagant Scout Scope With Leapers Accushot 1" Mount
If you own a Mosin Nagant you have likely considered mounting a scope, or have already spent tons of money mounting one. Many scope mounts require drilling and taping the reciever, bending the bolt and other such modifications. I won't call any of these "defacing" the mosin nagant, because, after all this is one of upwards of 17 million other mosin nagants.
I however, wanted to keep the overall look and feel of my rifle the same, while installing a sturdy scope. A few days ago I ordered the Leapers Accushot 1" scope mount and made a breif tutorial on installing it.

Overview/Supplies
Ultimately the goal of this instructable is to install the mount in a such a way that it wont budge, even after the massive recoil of the surplus 7.62 x 54r ammunition.
Note: I am starting with the assumption you have already removed the rear sight from your rifle. These adjustable sights can range from very easy to near impossible to remove. Mine came off extremely easily. If you are having a hard time, don't despair Heat and elbow grease will dislodge it.
Supplies:
Leapers Accushot 1" scope mount
I purchased mine off eBay, though amazon and many other online store carry them. You may be lucky enough to find them locally.
White out, or other such liquid paper
Blue painters tape
7/64" machine screw and cap OR original Rear sight pins
Medium Thread lock
Tools:
1/8" (preferably) metal drill bit
Drill/Dremel
Triangular or flat Bastard File
Rounded or half Bastard File
Vice Block
Optional:
Metal Blue - I use an old tin of Birchwood Casey I found in my Dad's gun box (this stuff is probably 20+ years old, but still works!)

Reality Check
Unless you have a rifle that is: rare, uniquely dated, pristine condition, has been handled by Joseph Stalin, decommissioned sniper, Finish, has matching dates, etc. Modifying your rifle is not the end of the world. The truth is at least 17 million were made and so many have been kept "stock " that it doesn't matter if you make yours the way you like it. Most people bought the rifle because it was cheap, and it is cheap for a reason. It is a 70 year old gun. It is moderately accurate.
Personal Opinion:
Just don't BUBBAFY your Mosin Nagant. Make it your own, just but don't pull a Bubba
The Mosin Nagant is, on its own, a very beautiful rifle. It is OK to leave it as it. In some cases,even, it is alright to slightly change its appearance But its iconic look will always stay the same.

Marking and Cutting
For most, this will be all they will need to do to prevent the mount from loosing zero. Essentially we are removing a small amount of material from the rails that clutch the dovetail in order to install a bolt that will keep the scope from moving.
Start by positioning the mount where you want it to be installed.
NOTE: this mount may require you to remove or modify your upper handguard. If you do not feel comfortable with this Leapers make smaller mounts, however the same steps can be used to accurize the mount.(SEE LAST PICTURE)
Mark just above the pin holes on both sides using white out to make your marks visible.
Once you have marked both sides remove the bolts and tighten the main body in your bench vise. Start with your flat bastard and mark small grooves for your rounded file to follow. Its a good idea to check the alignment of your grooves periodically to make sure you are still on track. The main body does not need much material removed to clear the holes. Now its on to the side rail.
Clamp the rail the rail into the vice again and follow the same procedure as the first, carefully checking to make sure the alignment is still good. When you have finished with both, reattach the main body to the rail and check to make sure everything lines up on the dovetail. You may find you need to remove much more material on the side rail than you did on the main body. If at this point you need to remove any additional material to make it fit, tighten down the bolts and clamp the whole assembly in the vice.
Check to ensure good fit using the smallest Allen wrench provided with the mount and poke through the pin holes. it should slide through freely.

Making an Indent for the Vertical Set Screw
For those of you who want to be extra sure your scope stays in place, you may want to take advantage of the small set screw underneath the scope ring. The best way to do so is to make a small indent in the top of the dovetail for the set screw to rest.
First you will need some way to mark where you plan to drill.
Here is the easiest way:
Put a small piece of blue tape on the rear of the dovetail. Use a marker to put as much ink on the tip of the set screw. Mount your scope like normal, being sure alignment is good. tighten the set screw firmly down, then remove the mount. On the blue tape you should now have a mark of where to start drilling.
Drilling:
To drill mine i simply used a normal all purpose 1/8 inch drill bit. I found that it went just deep enough to suit my purposes however, use of a proper metal bit may result in a deeper indent. Now to check your work loosely mount the scope like normal, but do not align it with your marks. Tighten down the set screw until you feel it begin to apply pressure then move the mount back and you should find it comes to a rest in the divot you have just made.
With the set screw removed you can clearly see the hole you have just made for the screw to set in

Putting It All Together.
You may choose now to reinsert the stock pins that came with the rear 91/30 sight, or you may bolt the assembly together I choose to bolt together, as it made me feel as if it was more secure, but the mount will be just as secure using the pins.
I used a small bit of blue to touch up the indent on top of the rifle and also on the scope mount. I also blued the bolts I used to give it a more uniform look. If you don't have blue, and don't feel like spending 15 dollars, a small bit of modeling paint would do nicely.
Installing: Align the mount, then put a drop of thread lock down in each of the bolts before tightening down. Insert the pins ( a bit of thread lock here doesn't hurt either) to prevent the scope from walking back. If you are using bolts to the same and make sure to use thread lock. Then completely remove the set screw and coat in thread lock before tightening down firmly.
