Mosin Nagant/KJW M700 conversion

That is one gorgeous gun you got there toast! Keep up the good work!

I like how you took the paint off the receiver. Good idea. Looks more and more like a Mosin every day.

Thanks for the interest!

1)I made mine from individualy bought parts, not a complete gun, (which I would implore you to do as well) so I can't speak to the compatibility of the real barrel. What I did was cut off M700 receiver at the meeting of the receiver and the upper hanguard and then use a 1/2" pipe for the rest, supporting it inside the hanguards with epoxy putty. 1/2" is actually too small so 3/4" might work better.


2) For sights on the Mosin I have no idea as I bought the sights individually from Ebay. As I understand it some were pinned and some were welded, either way you're probably in for a fight. Junior hacksaw if you really have to! Buy 'em on Ebay, cheap, easy and ready to go.

3)That big pin stayed in in my gun and I 'machined' (dremeled) the M700 to fit around it which meant removing two small tabs at the front of the receiver.

4)Actually it was a lot of work but not very difficult. I sat on my living room floor with (gasp) a routing bit in the extension for my dremel and just ran it round freehand occasionally checking which bits of the receiver were interferring. Took an afternoon but eventually I got it right. Be conservative, you can always take wood away but it's tough to put it back.

I hope I am not bothering you with my questions, but I´m like of a bit afraid in breaking up this beautiful gun:

I have to say though that if you're Mosin is complete then don't kill it! Keep it, shoot it, enjoy it, research the history and find out about it. It killed me to dremel out the stock I had because it was an actual wartime example! I know there are millions out there but I'm kinda sentimental like that

The parts I used came from Ebay and were very cheap. There are stocks available all over the place and, because it's not going to be a real gun, condition is not important. In fact the more messed up the better as far as I'm concerned. Rear sights, front sights, mag/trigger guards, barrel rings, cleaning rods, all are there and cheap. The M700 cost me 60, the stock 35, the mag/trigger guard was 15, the sights 15. Total that up and it's the cheapest gun I have!

Thanks for the questions and good luck!

Awesome! Well good luck, feel free to hit me up with questions of you have any.

Eventually I'd like to get the rear cocking peice and the bolt done right which will involve buying the real steel parts and then cutting and modifying them. If you have any information on how you got dealt with the real steel parts I'd love to hear about it!

Thanks.

Looks fantastic so far!

The inner barrel for me was just a cheap length of 1/2" pipe that I sleeved inside the forward part of the receiver and epoxied in place using epoxy putty (easy to work with). You can support the inner barrel by making spacers with electrical tape. You should only need one. 1/2" pipe is actually a little small compared with the real barrel so perhaps 3/4" would be better?

For your mag assembly you may have a small problem. The mag has to be perfectly aligned horizontally and vertically with the bolt so as not to leak gas when it shoots. Basically the brass nozzle on the mag must line up perfectly with the rubber inlet in the bolt. The only easy way to make sure it's perfect is to use the original magwell. I put the whole assembly, upper and lower receiver, into the gun so that I can be certain that it all lines up just as it did in the M700. It may be difficult for you to get the alignment right without the magwell although yours will certainly look more authentic!

Have you tried making a custom speed loader? Is it easy to load the gas from the top? I've wanted to build a gas-based Nagant sniper for my wife as she isn't strong enough to rack the bolt on my EDGi-upgraded springer.

Anyway, beautiful rifles, gentlemen!

...you are right, thats a promising idea . Well in my case it will be a summer-rifle only, a second thing that annoys me . But nothing can be perfect.

But hey, lets keep in touch, Im very interested on your next MN-Stock experiments. Our crew wants to switch to WW2 anyway, and everybody wants a carbine like rifle. I´m very eager on conversions in general. And its good that we can learn from each other....

EDIT: final touch with front sight and Hop-Up-Wheel:

I am pretty sure Ersatzjack did this on one of his Mosin Nagant conversions but the new thing I have done to move the bolt handle forward to where it should be is weld a real bolt on to bar stock and then weld that to a steel bolt ring. I'm in no way an awesome welder so this looks a little ugly but it is strong enough and I will just epoxy putty over the ugly and paint the bar stock and ring flat black. I think it makes a nice effect though.

I like the scope. Looks nice. How is it mounted, and can we see a picture of other side. Is it sturdy or just connected for looks? I would consider the investment too if you have found a good way of mounting it.

perfect, CO2, thats splendid! how did you get a CO2 system inside?
I am curious about your bolt idea too.

the PU scope is a Replica from Russia. The set contains already the mount, so everything is for the ready. Problem still exists because of our M91/30 lack of a special area to attach the mount. Only Sniper-Versions of the M91/30 can carry them, ours not. So I just connected the mount to the wood. Thats stable enough but the scope sits not exactly in the gun-middle (ca 1.5cm to the left). Thats a bit annoying but as far as I can see there is no other way of doing it.

here some Pics:







here the original M91/30PU for comparison:

Ok here we go again! Lovely scope btw carcosa, I love the look you've got there.

Well, this is a relatively easy conversion and damn me if it didn't actually work! I took 3/8" bar stock, dremeled and hacksawed it down so that the cut section would fit inside the reciever once it had been dremeled for space. Then it would be able to rotate with the bolt inside the rear reciever. I epoxied this to the rotating part of the bolt and then attached the bolt handle. I cut a slot in the rear reciever so it could run back and forth and that was that! Bit of extra metal removed from the reciever to make space overall and to make it closer to the real thing and this was the result (not painted the cut parts of the reciever yet):

Excellent job on the bolt. I wouldn't think it would be good to do with a VSR base but it works great on a gas gun.

Ok, last set, promise!
Done the tailpeice by hacking apart a real one and epoxying in place as close to the real position as possible. It's not perfect but it's close. The end peice is actually attatched to the cocking peice so it moves when the gun is cocked and fired. This needs to be cleaned up and then re-sanded to remove epoxy overflow. Once the metal has tarnished it's an epoxy grey anyway so it won't show up anywhere near as badly. After stress testing the bolt I managed to break the handle off (five really good slams) so with the stud I now installed it should be rock solid. I think it *might* even work for a springer but I wouldn't bet on it. I had to cut a real bolt, the receiver and the airsoft bolt to shreds, swear, sweat, burn, bleed and kill a dremel, countless cutting wheels and one junior hacksaw but it finally has the right bolt! Can I go home now?.....













Btw the bbs and gas go right in through the breach. I removed a small amount of metal for access to the gas valve but the bbs are a little tougher. I'm gonna make a feed tube for a speed loader but I haven't had time to do it yet. Carcosa made one that appears to work well. Best part is that it's actually a little quicker than removing and loading/gassing the mag (I only have one per gun, they're expensive you know!) and you can use the Mosin ammo pounches to hold speed loaders
