I had a lot of fun learning about the 7.62x54R (rimmed) caliber, the longest continuously utilized military round.

1. Mosin Nagant rifle (in cosmoline!) $129 + tax [included bayonet, tool kit, sling etc! ]
2. $10 to buy mineral spirits; disassemble everything and clean; reassemble. [read directions, youtube is a big help] A little gun grease around the trigger assembly makes it a nicer feel.
3. Bought one box of S&B 180grain ammo; dies from Lee.
4. As expected, front sight post is low, rifle shoots high at 100 yards. Also, realized that with my eyes and thick lenses, I can't SEE a 3" target at 100 yards in the position needed to use iron sights -- varilux eyeglass lenses induce distortion due to angles involved. A bit of wire-insulation over the front post solves the elevation but not the eyeglass problem.
5. An excellent scope mount kit that requires no receiver drilling is available (using a band around the receiver) -- but it is pricey.
6. Also excellent bolt handle replacements are available to get the handle out of the way of the scope -- but again, $ involved.
7. This is the largest caliber I've every shot and it does have a kick!
8. Elected to fashion a scope mount out of relatively hard 2x4 wood. Cut 1.25" hole with hole cutter, then bisected that hole to create a rounded edge that would fit the receiver. Drilled another hole to allow me to still see the iron sights if desired. Set height as desired, rounded top edge. Double stick tape on the inside of the round to better match receiver, and then an auto hose clamp fitted with a rubber hammer helping to make band fit the bottom of receiver. Note that I'm LEFT handed, so I put the hose clamp screw mechanism on the 'far' side for me. Then a short piece of scope rail on top with wood screws, short rings.
9. I didn't get the scope rail just perfect, so I compensated for left-right and up-down angular errors by inserting layers of aluminum ductwork tape on applicable edges of the ring attachments and also inside the rings as needed to get the scope within its adjustment range -- being able to see the already-sighted in iron sights was a big help here. You could also use thin brass shimming (I didn't have any). Or just drill/cut straighter than me. The scope mount actually feels pretty solid. Lightweight 4x cheap scope. This is not a fancy set up, so I didn't bother to ream the insides of the rings.
10. Fired up the oxyacetylene torch after re-disassembling the bolt so I can work on just the handle portion without messing with the hardened portions. Clamp applicable bolt portion in vise in safe area, heat portion of stemp to red hot while pulling with set of pliers on knob -- took three tries to get it where I wanted it. You can easily clean up the surface with 400 grit wet-to-dry sanding paper afterwards. Gets rid of the discoloration induced by the torch. Careful -- HOT. Also file/grind as desired.
11. Walmart has really inexpensive flipflops for the summer season, $2 got me a pair. Outlined stock but, cut out two thicknesses. Contact Cement seems to do the best job gluing these and also to the steel butt end. Wow, what a reduction in perceived Kick!
12. Target is from my first efforts at zeroing at 100 yards in a downpour from Tropical Storm Beryl. Ammo is reloaded (full length, then neck sized to be certain not to have crooked necks); mild load Varget 41.5 grains, 180 grain Sierra. This is way way better than I can do with iron sights. [The two far right shots are wild shots early in process; you can see my trek adjusting the zero downwards.]

Tons of fun for very little outlay. I may add a 45 degree support bar to better hold the rear of the scope rail, away from the bolt handle, if that seems necessary, later.

Mosin Nagant Rifle: $129

Box of 7.62 x 54 ammo: $19.50

Walmart Flip-Flop recoil pad: $2

Bubba Scope Mount: Priceless...
 
Personally, I wouldn't have shown that to anyone.

I mean, I know it's only a Mosin, but jeez, man.

Besides, there's no way you can have any kind of cheek weld with a mount that high.


I had my bolt handle cut and replaced with an angled press-in handle, and mounted and epoxyied a low-buck scout rail on the rear sight base then used an inexpensive LER scope. Cheap but effective (and not that^).
I also chopped the barrel down to 21" and bedded it into an ATI stock after floating the barrel, then Duracoated a camo finish onto it, so it's actually a pretty nice rifle now.
 
I had several knee pads left over from an appleseed and with three or four I had a great cheek weld! A bit of wood, some work with a knife and sandpaper and two dowel rods and I'll build a removable cheek piece for a couple bucks. Maybe this weekend. I've got some much more expensive rifles (6ppc 7mm08 mp15) but THIS is at least as much fun for maybe a third or a fourth the price!

Hey kcshooter-- did you have a gun smith shorten it or did you do it yourself. (and if so how)? Did the lands end up sharp at the muzzle ?

I cut it myself to make sure it was the length I wanted, (started at 24", stopped at 21") then had a local 'smith finish and crown it. Beveled the outside lip and it's a beautiful crown job.
I think it cost me a whopping $12.


(Sure, it wasn't flip-flops and hoseclamp cheap, but neither am I....)

Kcshooter -- sounds well worth $12! Does a regular hacksaw work for the initial cut? I might get mine recrowned-- lands don't look that sharp. Slugged it and may try .311 projectiles also as grooves are .313. Thanks again for the info.
 
It's pretty clever. The down side is it's likely to start to shift over time due to the uneven pressures and recoil.

If you're going to break with convention you might as well go all the way and use your ad hoc methods to do something nobody else does. An offset mount. Use the stock wood itself as the base. It's not perfect, but it will hold up better than a c-clamped and shimmed base. And just set your mount up horizontal to the bore so the scope sits just off to the left. Use your left eye for the scope, your right for the irons.

Yep, that's all I used, but I did use the expensive SnapOn blades, I highly recommend them. He then ground and polished and made it pretty before crowning. I think recrowning on anything military surplus is a good idea.
I did bring in a completely stripped barrel only to him which is why it was so cheap. If you bring in an undissassembled gun you'll get charged for disassembly too. Keep that in mind.
We've also gotten to be friendly over the past several years, so I might have gotten a deal, but I still can't imagine it would run you more than $20. And if your crown is dinged, fixing it will bring some accuracy back out of the gun.
 
I would have just used a couple of zip ties and duct tape to mount the scope.
I actually tried zip ties, but they are actually thicker than the auto hose clamp. So I switched to the hose clamp. I had to inlet the stock a tiny bit with the Dremel tool to make room for the thickness of the hose clamp. But it wasn't much.
 
There are far worse ways to pass a rainy day.
You obviously had a good time on the cheap and if you dont find it long term functional you did no permanent harm to the rifle.
Should you decide on something lower I saw a simple rear site replacement mount on Buds website for around 40 bucks.
Glad you had fun with the project.
 
Doc, search for the thread called "Accurizing The Mosin Nagant Rifle: A How-To Guide..."

It'll show you some techniques to accurize your rifle on the cheap. It includes some excellent ideas on a trigger job that I have personally used to great effect.

Your predictions were right and the scope didn't hold zero very well, primarily due to slop in the double stick tape and screws holding the rail to the wood block. I elected to remove the double stick tape, put in epoxy glue in the screw holes, reinstall screws and use the glue to better secure the rail to the wood. I also added a metal strap (89cents) cut from a hardware strap, to avoid vertical movement of the rear portion of the rail. [I shoot left handed, so I put the strap where I prefer.]

With these improvements, first effort was a 3-inch group of 4 shots at 100 yards. It feels way more steady.

MosinFreak: I went through your thread and may give that trigger mod a try! Thanks for the info.
