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.

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
– 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.
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.
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
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.
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.
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.
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.
