Hey guys. First off I have 0 percent experience at gunsmithing and do not plan to do this on my own. I am running this idea by you guys so that you can see if it is conceptually sound. Below is a picture of what I plan to have done to a Mosin Nagant trigger housing. The Magazines that will be used are chambered for 7.62x54r so there should be no issue there. I have see this done to other Nagants by the Polish (maybe not sure on the nationality). I know your going to laugh your ass off that i did this in paint but it is just to give the fabricator some Idea of what I am shooting for. Thanks for any help!



This is the one adapted by the Polish I believe. I cant find a better picture so I am just guessing on what is going on internally.



Thanks for any input guys I would greatly appreciate your help!


EDIT . Here is one I found of someone else attempting the build just for your reference.

Looks like an interesting project, for sure.  I don't hear anyone laughing.

Where did that magazine come from?  

It would make a good project for one of those dog M44's, like those Century 3-fer/$100 I have.

I would be concerned about conventional loading - it may make the rifle a bitch to load from the top.  You will have to mill out the receiver bottom to accomodate the mag, losing the interrupter while doing so.

Its a Lahti-Saloranta magazine and I hopefully will be doing this mod to my rifle I already had a bunch of work done to. Here it is.



Why do you think you would have to drill the receiver? The magazine narrows to a single stack at the top.

So you're cutting the trigger guard/mag assembly in half, chopping out the mag, & welding in a mag well?  You've got a beautiful Mosin.  I've got 7 Mosin actions, and my only question is, why?

Essentially yes after I do alot more research and debate it some more. Because this is going to be my long range rig and I want to be able to change magazine quickly instead of having to load rounds 1 by 1. There is a magazine extension that is coming out but that still requires me to load rounds 1 by 1.

Obviously you've put a lot of money into it.  That's my question.  WHY is it going to be your long range rig?

Mainly because I am inexperience at long distance shooting and this is a cheap way to get started. This rifle cost me less actually than most put into their long range rifles even with all the work done on it. I came in at just a little over 1k for everything you see here. Ammo is super cheap compared to the other calibers . And also I want to be unique.

There are 2 things I am running into with this project so far. I would need to widen the receiver to accept the magazine. Some told me that the interrupter would have to be lose, but I believe that if the rifle is using a magazine that negates the purpose of the interrupter. So that first part can be handled if I can be sure that the safety of the rifle isnt at risk by removing metal from the lower part of the reciever.

Second issue is the magazine needs to be opened up more on top for the locking lugs to pass through the magazine. This is the part that truly is giving me the most trouble. I cant think of a way to have the magazine be wide enough for the rounds to get picked up by the bolt but also stay in the magazine. I am going to have to brain storm like crazy on tha tpart.

Interesting rifle - particularly like the side mount.  What bbl are you using?

Why does the receiver need to be widened?  You'd have to cut a receiver in half, which would make getting your bolt raceways straight again extremely difficult.  Didn't you say this is a single-column magazine, just like the original?  If so, why do you have to cut receiver metal?  Why are there any problems w/ the bolt lugs chambering a round?

It'll be @ least as wide as the original magazine.  That said, you'll have to remove wood from the stock, and if you're planning on welding in a magazine well, that will have to be as wide internally as the new magazine, and externally slightly wider, requiring even more wood be removed.  I don't fully understand the need for a metal magazine well - I would think wood would do just fine.

Its a uk-59 machine gun barrel that has been turned down in a lathe. The magazine starts off as a double stack and works its  way down to a single stack but it still isn't skinny enough to be high enough for the magazine to get to the feed ramps.  There is also a issue with the locking lugs being larger than the feed lips of the magazine it has to pass through. I hope this is some what of a clarification.

going to say keep it up.  I love seeing different guns on the line.  I think you should ruin a $90 gun before you start playing with that one.  Just to make sure.  Have you ever though of PSL or draginov mags?  Not sure if they would work better.  Best of luck

used Savage model 10 with 16x Super Sniper scope is quiet a bit uner 1k. add a CDI AICS bottom metal and mag and you're still uner $1k, with a proven performer. projects like yours are fun though, hope it works out the way you planned.

I'm currently working on a project Mosin and I have to say, this is an inspiration.  Bravo!
