Mosin Nagant Modifications

Top 10 Mosin Nagant Modifications

When I originally looked for potential modifications for my own 91/30 Mosin, I scoured the web searching through forum after forum listening the opinions of a wide range of Mosin owners. However, there was no definitive list of modifications that should be done. This is the list. Below you will find the culmination of all my research, the 10 most popular Mosin Nagant modifications along with a description and links to reviews and up to date pricing so you can set up and start your build.

Top 10 Mosin Nagant Modifications

  1. ATI Monte Carlo.
  2. Timney Trigger.
  3. Muzzle Brake.
  4. Bipod.
  5. Bent Bolt Handle.
  6. Scope Mount and Scope.
  7. Re-crown the barrel.
  8. Floating the Barrel.
  9. Safety Pull Tab.
  10. Buttstock ammo pouch.

1- ATI Monte Carlo

This is an aftermarket synthetic stock, lighter than the original mosin stock. Weight is a big issue with this rifle and a new stock is the biggest improvement that can be done. In addition to the weight, the look is incredible and won’t break the bank.For those looking for a scope, there is a package available with this stock that includes a scope and mount for not much more than the stock alone.

2- Timney Trigger

No matter what choice you go with in regards to the stock (aftermarket or refinish) the trigger is without a doubt the next obvious choice. Pulling the stock trigger is rough, to say the least. It creaks, it jumps around, it’s not consistent, and it’s everything you don’t want in a trigger. The Timney trigger fixes this problem and with all the research I have done on Mosin upgrades, this is the one and only choice of Nagant enthusiasts. It’s crisp and makes this Russian cannon go Bang with ease. This trigger also includes a built-in safety (a massive improvement over the original) and the trigger pull is adjustable.

3- Muzzle Brake

Besides adding a completely new look to the barrel. The muzzle brake greatly reduces recoil (your shoulder will appreciate it). This will also help improve accuracy from the decrease in muzzle jump.

4- Bipod

– regardless of which stock choice you go with, the mosin is still a large rifle and supporting its weight while aiming at a target a few hundred yards away is a challenge to contend with. This bipod will allow you accurately aim with much more stability.

5- Bent Bolt Handle

The original 90 degree bolt design on the Mosin Nagant works perfectly in a non-scope infantry situation. It is easy to slam open with your palm, but it is also easy to snag the bolt of pretty much anything. In addition you won’t be able to scope your Mosin with the traditional bolt design. A bent bolt allows for a sleeker look and the ability to add a scope.

6- Scope Mount and Scope

By now your mosin looks like a BA sniper rifle without the scope. It’s time to change that. You have a few scope and optic choices however the most common choice is the Aim Sports Long Eye Relief scope. It won’t break the bank but will get the job done. For the mount I recommend the Promag rail. It is without a doubt the most popular choice of those adding a scope to their Mosin Nagant. Now obviously you can spend a lot more on a scope. This will come down to personal preference, but keep in mind that a good Leupold or Nikon scope on a Mosin will only  highlight the accuracy the rifle is known for.

7- Re-crown the barrel

While not a must have if your rifle was made correctly and treated well during and after the war, I have read many reports of improvements in accuracy due to recrowning. The end of the barrel is the last piece of the gun the bullet comes in contact with before heading to your target. If the end is uneven (due to heavy wear or cutting from shortening the barrel), problems with the bullet being pushed to a particular side due to unevenly escaping gasses will be an issue. Without a lathe you will need a recrowning tool that can attach to a drill.

8- Floating the Barrel

If you choose to refinish or keep the original stock on your rifle then floating the barrel is a great modification. With such a long barrel there are lots of pressure points on the barrel from the stock. These pressure points can push the barrel especially when it starts to get hot from shooting. By free floating the barrel, the stock is sanded so that it only contacts the barrel at the ends of the barrel therefore improving accuracy.

9- Safety Pull Tab

If you opt out of the trigger upgrade discussed as #2 which includes a built in safety, then you are stuck with the original mosin safety. Not only is the original awkward, but it’s extremely difficult to use, not something I’m fond of when it comes to a gun’s safety. This pull tab attaches to the original safety and makes it easier to operate, making your rifle safer.

10- Buttstock ammo pouch

– With 7.62/54R ammo being so cheap, you’re going to want to have a handful on your rifle at all time. A nice buttstock ammo pouch is a simple and very practical accessory.


11- Comfortable sling

A heavy rifle with an uncomfortable sling is a bad combination. Use the same sling mounts on your mosin, but add a sling that won’t cut into your shoulder.

    1. I added the scope as it is a more popular mod than fixed sights, but I am putting together an in depth article on sight options which will include fixed sights. Send me a message if you would be interested in contributing some info to that article or others, especially about your sights.

  1. My Mosin is 95% original. I refinished the stock. I removed the rear sight, installed a UTG rimfire dovetail (3/8″ / 11mm.) to picatinny rail and have a NcSTAR 2-7X 32mm. long eye relief pistol scope.
    For recoil I have a large size LimbSaver. I shoot my own reloads, mostly 150gr. FMJBT so recoil is no big deal.

  2. I had a Mosin Nagant in it’s original condition for several year. Then I decided to upgrade it and make it more than just a weekend shooter at the range. After surfing the web, I decided on, and made the following changes:
    I put it in a stock from Boyd’s Stocks.
    I shortened the barrel to 22″ and put an 11 degree crown on it.
    Threaded the barrel and installed a muzzle brake from CNC Warrior.
    Installed a Red Star scope mount and a Nikon 3-9×40 BDC scope.
    I had the bolt handle modified by Max Shepherd Bolt Products.
    Installed a Limbsaver Recoil pad.
    The rifle is much more accurate than it used to be and is a pleasure to shoot. A Timney trigger is next on the list.

  3. a friend has a mosin nagant Remington It has been rebarreled to 30-06. It does not eject properly. I was told that it used to. Many smiths have worked on this gun to no avail. Can any of you please help me locate the proper ejector for him? Thank you in advance. We were not the ones that did the rebarrel job but we work with what were given. Thank you again

  4. I have an original Mosin when I heard about it I went and got one. I have bought rifles that rival it since, however I have seen the upgrades and shot one at a 600 yard range. It was beautiful and ran great it was accurate. The owner had to load one bullet because of the archangel stock takes the mag pull mags and didn’t work he said the spring was not strong enough. I need to know that others were able to empty the magazine running the gun. If not I am not sure I will go with that stock.

  5. Anyone know of a company or person out there making a modern style round bolt and reciever for the Mosin kinda like what’s on a Remington 700? I’m running a fluted 26 inch bull with tanker style threaded muzzle break, with a Crook stock from Ukraine, a rock solid scope mount, Timney trigger, and shooting self pressed brass cased ammo. Just looking to take this rifle further and running out of options.

  6. I am building a 1943 Izzy , (sorry can’t remember the spelling), I use a Jmeck scope mount , it uses a strap around the receiver ,no drilling , a little relief in original stock is required . Have a 40mm scope and home made bent bolt all works great . I’m fixing it up but nothing I can’t reverse also have a 1934 hex , love the history of these rifles , I often wonder when I’m holding it where it served , cool rifles.

  7. All these comments are valuable and entertaining to a degree. I’m glad y’all enjoy your Mosin-Nagants, what-ever version you have. I have MSRs, so I really don’t need to make an historic weapon more accurate than it was designed to be. I tend to learn to shoot the weapon the way it was designed to be shot, rather than modify the weapon to the way I shoot. And I’ll tell you what… I get some amazing results. My Finn-Mosin-Nagant is as accurate as I am. And fun? You bet your arshini it is. I routinely use it for hog and deer hunting, sans scope… with effect.

    My recommendation? Just enjoy the historic nature of the rifle and shoot the damn thing!
