Mosin Negant project finally finshed

[Jekemi]

With just a few days to spare I’ve finally completed the Mosin Negant modernization project.
•   New synthetic stock
•   New drop-down bolt
•   New hex screws and aluminum bedding pillars
•   I machined and built the scope mount from inexpensive aluminum alloy bar stock, black socket screws, high-temp paint, and JB Weld (they wanted $90 for a new one)
•   New trigger pin
•   Shortened and re-crowned barrel
•   New scope, rings, and scope brackets
Now I just need to clean it up, polish the bore, sight it in, and my son is ready to hunt deer on October 15th over in Eastern WA. It was a fun project that took more time than I reckoned, mostly working on the scope mount. Many thanks to those on HuntWA who offered valuable advice. If you want a detailed, step-by-step let me know. Just email me.

Can you see through that scope with the rifle normally shouldered? I only ask because it looks like the scope is centered at least 3" over the bore.

[PA BEN]

Looks more like 4"

Interesting.  Never seen one sporterized like that...

Scope seems a little high.  That rifle is going to get some second looks and start a few conversations.

FC. yes I can see through the scope normally shouldered. I haven't done any adjustments or fine tuning yet. Just finished the project this morning. I have tons of cleaning up to do and lots of work to do on the barrel. I hope to take it to the range on this Saturday. Any suggestions or recommendations you have are greatly appreciated. I may be asking you all for additional advice after Saturday's initial shoot. The gun feels very heavy and a little bulky but I won't be carrying it in October. My 22 year old, 6' 5" son, who is in great shape will be toting the gun.

Please take this with the kindness intended: that rifle will be very difficult to shoot at varied ranges due to the scope height.  You will find that the usual 2" high at 100 yards idea will not work well at all. If you set it 2" high at 100 it will shoot about 8-10" high at 200, if you set it equal to the distance in height from scope center to bore center at 100 you will hit maybe 4-6" low at 200.

The tough part is when you have a moment to take a quick shot, you have a good rest but little time due to the fact that the animal is only 30 yards away...Where on that animal do you aim? High...or low...FWIW I don't give that JB weld long against rifle recoil.

If you can get that scope down tighter to the barrel you will have a much better time of it. A mount like this one here will get the scope down as will one of the scout type mounts.

Scout mount. Use a long eye relief (pistol) scope with this.

FC, thanks for your comments. The problem I had was that the mount had to be sufficiently high in order for the bolt to clear the mount. I could have used a much thinner top bar, which would have brought the scope down about 1/4".
The mount is screwed into the receiver and into the rear sight bracket. The JB Weld is simply a little insurance. I used black socketed 10/32 machine screws. It is a solid mount.
The other problem I faced was that the 50mm front objective wouldn't clear the rear sight bracket. This required me to use high scope rings. I could try mid-height scope rings. 
I didn't want to go with a long eye relief scope, which would have solved both problems; bolt clearance and front objective clearance.
This may be my only solution however.
Again, your advice and consultation is greatly appreciated.

What I have seen done in those situations is removing the bolt handle and rewelding/bending it to clear a scope. It may not have been practical in this situation though as my experience with these guns is limited.

[Jekemi]

jeepasaurusrex & FC: Thanks for your comments. I sent the original Mosin bolt (sticks straight out) to be replaced with this drop down model. But, when I slid it in place it hit the mount. I added and additional spacer as you can see. The bolt still just barely hit the top aluminum bar so I grown down the right rear edge to clear the bolt. As I see it there are 4 things I can do at this point.
1.   Use a thinner top bar, I have one; I just need to drill it and mount the scope brackets.
2.   Use mid-high scope rings (short rings don’t allow the scope to clear the rear sight bracket)
3.   Get a 3x9x40 scope, which has a smaller diameter front objective
4.   Use a long relief scope (I don’t want to do that)
I believe that if I follow the first three steps I can get the distance from the scope center to the bore center to 2" or 2 1/2 inches, which is acceptable. What do you guys think?

[jeepasaurusrex]

Didn't the originals have the scope mounted to the side?

It seems the high mounted scope is the norm on them.
I wonder if a cheek rest on the stock would improve stock to cheek meld?

Found this pic online. It looks like the scope is sitting a bit lower than yours?

That is sick man! Beautiful!

Thanks for sharing.

You need to copy the scope mount in the pic above. The base needs to be far enough forward to clear the bolt handle and the scope rings close enought that you can slide the scope back so the rear ring is aainst the turrets.

[FC]

If you can get that thing down to 2" or so I would say you are in business.

[carpsniperg2]

looks like you did a fine job!
