Mosin Nagant Upgrades: 6 Key Upgrades And Product Recommendations

The Mosin Nagant is a legendary gun. It has been around since World War II and was one of the major weapons for the Russians. Its design was quite revolutionary then, but it is outdated by today’s standards. It is heavy, kicks hard, and has no provision for optics, and its finish is rugged compared to modern rifles, which have a rather sleek finish. In this article, I’ll show you some Mosin Nagant upgrades that will kick this legendary gun up a notch.

With a few accessories, you can upgrade your Mosin Nagant from an old, heavy, and hard-to-shoot rifle to a fun-to-shoot gun with minimal recoil and noise that handles better. Some of these accessories are easy to find on Amazon at an affordable price. Many are easy to install yourself without drilling on the gun, but you may need to hire a gunsmith for others.

6 Key Mosin Nagant Upgrades And Product Reviews

Mosin Nagant Upgrades

Below is a look at the six most crucial Mosin Nagant upgrades and a review of suggested products for each upgrade.

Mosin Nagant Upgrades: Stock

The stock is one of the most important Mosin Nagant parts. It provides the shooter with a means to brace the gun and aim with stability and counters the muzzle rise and transmits recoil to the shooter’s body. It supports the barrel.

Chances are your Mosin Nagant stock is old, worn out, and rusty. As such, it might feel heavy and compromise stability and shooting efficiency. Therefore, you should replace it.

There are different aftermarket stocks on the market compatible with various types of Mosin Nagant. They vary in shape, size, finish, and material used. Below is a brief overview of the best stocks for a Mosin Nagant.

Mosin Nagant Upgrades: Trigger

Once you have chosen a stock, the next important step is choosing a trigger. The M91/30 trigger in most Mosin Nagant guns is rough, snobby, creaks, and jumps around. Therefore, you want to replace it with one that pulls smoothly for accurate shooting.

Alternatively, you can have your gunsmith do a trigger job that involves adding a return spring on the existing trigger to improve slack take up. They would also need to scrub the trigger assembly to improve its feel and handling.

Most Mosin Nagant gun owners may be adamant to fit an aftermarket trigger on their stock due to safety and efficiency concerns, there are a few options on the market that ensure safety and efficiency. The best choice for a trigger for your Mosin Nagant is the Timney Trigger.

Timney Trigger

  • Pull weight range: 1.5 – 4 pounds
  • Outstanding features: adjustable pull weight, thumb safety

The Timney trigger enables more accurate shooting when using your Mosin Nagant rifle. It comes fully calibrated and ready to shoot and enables you to adjust the pull weight, sear engagement, and over travel. It has an aluminum construction that ensures your stock remains light.

The trigger is curved for ergonomic handling and has a single-stage operational design with little to no distance in pull weight between the travel and break stage. One of its most unique features is the thumb-operated safety that eliminates the Mosin Nagant’s cocking knob safety, which is cumbersome to operate.

At the factory, the pull weight is set at three pounds. However, you can adjust the pull weight between two to four pounds, depending on the shooting conditions and the weight of your rifles. Two to 2.5 pounds is most suitable for lightweight rifles and target shooting from a bench.

A range of three to 3.5 pounds is the most common for different shooting scenarios, including three-gun competitions, hunting, and target shooting. Four pounds of pull weight is suitable for heavier rifles and shooting in cold weather conditions with your gloves on. Note that setting the weight too low may increase the risk of accidental discharge.


  • Compatible with a wide range of rifles
  • Adjustable pull weight
  • Factory calibrated
  • Fitted with a thumb safety
  • Operates smoothly


  • You may need to ship your stock to Timney or hire a gunsmith to inlet it

Scope Mount

When Mosin Nagants were being designed, the sights and scopes technology had not emerged, so the rifle construction did not incorporate scope mounts or sights. To modernize your Mosin Nagant, you will need to install a scope mount on the rifle. Below is an overview of one of the best scope mounts for Mosin Nagant rifles.

AIM Sports M44/Mosin Nagant 91/30 Scope Mount

  • Weight: 62.5 g
  • Dimensions: ‎5.3 x 1.4 x 1 inches
  • Outstanding Features: compatible with all weavers standard rings

It has a simple minimalistic construction of an aircraft-grade black anodized aluminum finish and is compatible with most scope and sight models for M44, M39, and Chinese type 53 rifles. It accepts all weaver standard wings. Since it is short and it does not go all the way to the front of the barrel, it is most suited for use with a rear sight.

The main disadvantage with this mount is that it is difficult to install. Most people install it over the existing leaf spring. However, it can be quite challenging to line up the holes and insert the hinge pin. You require two cramps at different angles to get the alignment right. Note that exerting too much torque on the clamps can damage the mount. However, once you mount it, the installation is quite sturdy.


  • Quite affordable
  • Lightweight
  • Compatible with most scopes and rear sights


  • Difficult to install
